1. Introduction
1.1. Background BHP Billiton Iron Ore Pty Ltd (BHP) currently operates a number of iron ore mines and associated rail and port infrastructure within the Pilbara region of Western Australia (WA). Current mining operations include the: · Newman Operations consisting of the: o Whaleback Hub (consisting of Whaleback Pit and Orebodies 29, 30 and 35) hub located approximately two kilometres (km) west of Newman Township; and o Eastern Ridge Hub (consisting of Orebodies 23, 24, 25 and 32) located approximately 5 km east of Newman Township; · Mining Area C (MAC) Hub (consisting of the MAC and Southern Flank mining operations) located approximately 90 km north west of Newman Township (Attachment 2A); · Jimblebar Hub (consisting of Wheelarra Hill (Jimblebar) Mine, Orebody 18 and Orebody 31) located approximately 35 km east of Newman Township; and · Yandi Mine located approximately 100 km north west of Newman Township. Ore from the Newman Operations, Mining Area C, Jimblebar Hub and Yandi mine is transported to Port Hedland via the BHP Newman to Port Hedland Mainline (and associated spur lines). Ore is then shipped out through Port Hedland at the BHP facilities at Nelson Point and Finucane Island. 1.2. Purpose of this Document MAC is currently approved under Ministerial Statement 1072 (MS 1072) (Attachment 5A) and Environmental Licence L7851/2002/6 (Attachment 5B). BHP is seeking a works approval to construct a new surplus water scheme at South Flank (the Project). The works approval application for the Project seeks to: · Construct a new managed aquifer recharge (MAR) scheme at South Flank consisting nominally of 10 reinjection bores1 (Attachment 2A) to dispose of up to 12.76 giga litres per annum (GL/a) of surplus mine dewater; and · Construct a surface water discharge scheme in Pebble Mouse Creek to dispose of up to 12.76 GL/a; Prior to environmental commissioning of each scheme a compliance report will be submitted to the Department of Water and Environmental Regulation (DWER). Depending on the timing of construction activities a separate report may be submitted for the MAR and discharge schemes. Following the completion of environmental commissioning of each scheme a report will be submitted to DWER detailing any issues identified and corrective actions undertaken. Following submission on this report BHP will: · Submit an application to amend Environmental Licence L7851/2002/6 to include the commissioned scheme; and · Commence the time limited operation of the commissioned scheme.

4 South Flank Surplus Water Scheme Works Approval Application Supporting Document Infrastructure Characteristics Relevant The following environmental factors associated with the Project are considered to require Environmental Factors specific management measures as detailed below: 1. Noise and dust (construction only); 2. Groundwater 3. Surface water. 4. Subterranean fauna; and 5. Vegetation. Application Commitments Section Construction Dust will be managed via water carts. Table 5 All clearing will be in accordance with the approved MS 1072. Table 5 Prior to environmental commissioning of each scheme a compliance report will be submitted to the 1.2 Department of Water and Environmental Regulation (DWER). Depending on the timing of construction activities a separate report may be submitted for the MAR and discharge schemes. Commissioning The MAR scheme will monitored (Table 4) to confirm that groundwater mounding does not intersect Table 6 with the root zones of vegetation or significant troglofauna habitat The water quality of abstracted groundwater will be tested monthly at the South Flank Turkeys Nest Table 6 (Table 4; Attachment 2A) during commissioning. Monthly water quality testing will also occur at the four monitoring bores (Attachment 2A). Reinjection and surface water discharge will cease if the water quality limits for the South Flank Table 6 Turkeys Nest are reached. The Pebble Mouse Creek discharge point will be inspected regularly during commissioning to Table 6 identify any erosion that may have occurred. In the event that erosion is identified additional erosion control measures will be implemented (e.g. extending rip rap) and if necessary repairs undertaken. Discharge into Pebble Mouse Creek will be managed to ensure it does not extend beyond the Table 6 Wetting Front Limit (Attachment 2A). Time Limited Operation / Operation The MAR scheme will managed (Table 4) to ensure groundwater mounding does not intersect with Table 7 the root zones of vegetation or result in a significant loss of troglofauna habitat in the Project Area. The water quality will be tested quarterly at the South Flank Turkeys Nest and the four monitoring Table 7 bores (Table 4; Attachment 2A) during Time Limited Operations / Ongoing Operations. Reinjection and surface water discharge will cease if the water quality limits for the South Flank Table 7 Turkeys Nest are reached The Pebble Mouse Creek discharge point will continued to be regularly inspected and additional Table 7 erosion control measures will be implemented if required.
5 South Flank Surplus Water Scheme Works Approval Application Supporting Document 2. Existing Environment
2.1. Climate Newman Aero meteorological site (007176) is the closest Bureau of Meteorology (BoM) station to the Project Area. Average annual rainfall at Newman Aero is 329.5 mm (BOM, 2019a). This is mainly derived from tropical storms and cyclones during summer, producing sporadic, heavy rains over the area. Mean monthly rainfall varies from 3.8 mm in September to 70.4 mm in February (BoM, 2019a). Daily rainfall is highly variable; the highest maximum daily rainfall ranges from 34.8 mm in October, to 305.6 mm in February (BoM, 2019a). The mean maximum temperature in summer months (October to March) is 35.2°C to 39.2°C, and mean maximum temperature in winter (April to September) is between 23°C and 32.1°C (BoM, 2019a). Wittenoom meteorological site (005026) is the closest station to the Project Area that records daily evaporation. Wittenoom is located approximately 110 km south south west of the Project Area. Mean daily evaporation at Wittenoom throughout the year is 8.6 mm/day (BoM, 2019b), which equates to 3.1 metres per year. Evaporation greatly exceeds rainfall in the region throughout the year and on a month-by-month basis (BoM, 2019b).
2.2. Nearby Land Uses and Sensitive Receptors The land use of the surrounding area is mining operations and exploration activities. The closest BHP sensitive receptors to the Project Area is BHP’s Mulla Mulla (5.7 km) and Packsaddle (9.5 km) Villages which are located within the Prescribed Premises. The Prescribed Premises is situated in a remote location, approximately 90 km north west of Newman. The closest potentially sensitive non-BHP owned receptors in the vicinity is the Hope Downs accommodation camp located 2.6 km south of the eastern end of the Project Area.
2.3. Soils and Landform The Project Area is located within the Boolgeeda, Newman, Platform, Pindering and Wannamunna Land systems as mapped by van Vreeswyk et al. (2004): · The Boolgeeda Land system is described as: “Stony lower slopes, level stony plains and narrow sub- parallel drainage floors, relief up to 20 m. A common system in shallow valleys below hill systems such as Newman and Rocklea.” · The Newman Land system is described as: “Rugged high mountains, ridges and plateaux with near vertical escarpments of jaspilite, chert and shale, the second largest system in the survey area and prominent in southern parts (e.g. Ophthalmia Range, Hamersley Range), relief up to 450 m.” · The Platform Land system is described as: “Narrow, raised plains and highly dissected slopes on partly consolidated colluvium below the footslopes of hill systems such as Newman, relief mostly up to about 30 m but occasionally considerably greater.” · The Pindering Land system is described as: “Level to gently undulating hardpan wash plains with surface mantles of ironstone pebbles and gravel, some patterns of small groves and minor tracts receiving more concentrated through flow; relief up to 10 m.” · The Wannamunna Land system is described as: “Level alluvial plains with prominent grove patterns of vegetation and shallow loamy soils over hardpan and broad internal drainage plains with deeper more clayey soils, relief up to 5 m. The system is found in south central parts of the survey area as broad flats within the Hamersley Ranges (Newman land system).” Soils of the Pilbara region have been defined and mapped at a scale of 1:2,000,000 by Bettenay et al. (1967). Four soil units occur within the Project Area: Fa13, Fab 14 and Fb3. · Soil Unit Fa13 is described as: “Ranges of banded jaspilite and chert along with shales, dolomites, and iron ore formations; some areas of ferruginous duricrust as well as occasional narrow winding valley plains and steeply dissected pediments. This unit is largely associated with the Hamersley and Ophthalmia Ranges. The soils are frequently stony and shallow and there are extensive areas without soil cover: chief soils are shallow stony earthy loams (Um5.51) along with some (Uc5.11) soils on the steeper slopes. Associated are (Dr2.33, Dr2.32) soils on the limited areas of dissected pediments, while (Um5.52) and (Uf6.71) soils occur on the valley plains.” · Soil Unit Fa14 is described as: “Steep hills and steeply dissected pediments on areas of banded jaspilite and chert along with shales, dolomite, and iron ore formations; some narrow winding valley plains: chief soils are shallow stony earthy loams (Um5.51) along with some (Uc5.11) soils on the steeper slopes. (Dr2.33 and Dr2.32) soils which occur on the pediments are more extensive than in unit Fa13. (Um5.52) and (Uf6.71) soils occur on the valley plains." · Soil Unit Fb3 is described as: "High-level valley plains set in extensive areas of unit Fa13. There are extensive areas of pisolitic limonite deposits: principal soils are deep earthy loams (Um5.52) along with small areas of (Gn2.12) soils."
6 South Flank Surplus Water Scheme Works Approval Application Supporting Document 2.4. Groundwater The Project Area lies within the following two regional aquifers: 1. Hamersley – Fractured Rock Aquifer: The Precambrian rocks of the Hamersley Basin are principally volcanics, shales and iron formations. Groundwater is contained within fractures within these rocks. The groundwater level may be deep below the surface, and is generally fresh. The main use of this aquifer is for mining and mine dewatering from iron ore mines. Bores have also been drilled for road and railway construction. There will be increasing dewatering from the fractured rocks around iron ore mines as the pits become deeper (DoW, 2015a). 2. Hamersley – Wittenoom Aquifer: The Wittenoom aquifer is distinguished as a separate aquifer system because the Wittenoom Dolomite is distinct from the other fractured rock aquifers in the Hamersley Basin, having karst development (solution cavities) and being overlain by a thick sequence of valley filled sediments consisting of pisolite, calcrete and alluvium. The Wittenoom Dolomite is the most important aquifer in the province and underlies the main valleys in the Hamersley Range; it is highly transmissive and high yielding where there is karst development. Water levels may be fairly deep. The groundwater is generally fresh. The aquifer has been developed for Tom Price and Marandoo water supply and has been investigated at other localities. There is likely to be significant development pressure on this aquifer for supply to iron ore operations (DoW, 2015b) Reinjection activities will occur in the Hamersley – Wittenoom Aquifer. Groundwater levels within South Flank Valley vary between 35 metres below ground level (mbgl) and 100 mbgl (Attachments 2B and 2C; Plates 1 and 2). The groundwater gradient is relatively flat throughout the valley with the majority of the variation in depth to groundwater due to changes in surface elevation. Generally, depth to groundwater is lowest in the areas of Coondewanna Flats and Weeli Wolli Spring where surface water and groundwater flow concentrates. Groundwater in the catchment typically has a low salinity with a typical total dissolved solids range between 600 and 700 mg/L. There are no public drinking water source areas within or adjacent to the Project Area.

Plate 2: South Flank Valley Southern Cross Section3
2.5. Surface water One named perennial watercourses (Pebble Mouse Creek) and a number of unnamed perennial watercourses flow across the Project Area. Pebble Mouse Creek is located within the Upper Weeli Wolli Creek sub catchment (Attachment 2A) and exhibits high inter-annual variability of streamflow, with long periods of low or no flow. Southern Flank valley receives drainage from the higher ground north of the main valley and from the north- eastern slopes of Mount Robinson. Drainage from the Southern Flank ridgeline generally passes through narrow valleys or gorges before reaching the valley floor. The valley floor drains into Pebble Mouse Creek which enters Southern Flank valley from the south and continues on to the east into Weeli Wolli Creek. Water quality in the catchment is considered to be good, with total dissolved solids up to 100 mg/L in Pebble Mouse Creek.
2.6. Flora and Vegetation The Project Area lies within the following two Beard (1975) Vegetation Associations: · 18: Low woodland; mulga (Acacia aneura) · 82: Hummock grasslands, low tree steppe; snappy gum over Triodia wiseana No significant flora species listed under the Environmental Protection Biodiversity Conservation Act, 1999 (EPBC Act) or the Biodiversity Conservation Act, 2016 (BC Act) have been identified within the Project Area. Two DBCA listed Priority Flora species have been recorded within the Project Area: · Aristida jerichoensis var. subspinulifera: Priority 3; · Rhagodia sp. Hamersley (M. Trudgen 17794): Priority 3; These species are wide spread in the local and broader region. All priority flora species will be avoided where practicable. In the event that a priority flora species need to be disturbed it will be undertaken in accordance with Ministerial Statement 1072. All clearing associated with the project will be undertaken in accordance with MS 1072. The Project Area intersects seven broad floristic communities with twelve vegetation associations (Table 2). None of these are representative of a Threatened Ecological Community (TEC or Priority Ecological Community

9 South Flank Surplus Water Scheme Works Approval Application Supporting Document 2.7. Vertebrate Fauna Biologic (2014) identified eight habitat types within the Project Area: · Crest / Slope; · Drainage Area; · Gorge / Gully; · Major Drainage Line; · Minor Drainage Line; · Mulga; · Sand Plain; and · Stony Plain. Two significant fauna species has been identified within the Project Area: · Falco hypoleucos (Grey Falcon): Schedule 3; and · Pseudomys chapmani (Western Pebble-mound Mouse): DBCA Priority 4. Active pebble mounds will be avoided where practicable. Any clearing associated with the Project Area will be within the existing prescribed premises and will be undertaken in accordance with MS 1072.
2.8. Subterranean Fauna 2.8.1. Troglofauna The geology of the MS 1072 Development Envelope comprises four habitat types relevant to troglofauna. These are ‘hardcap zone’, detritals, mineralised rock and BIF host rock. The South Flank MAR occurs within the detritals of the South Flank valley. Detritals can be divided into recent quaternary detritals and three classes of tertiary detritals. Quaternary detritals usually comprise a mix of ore and shale in a silty matrix and are regarded by BHP Billiton Iron Ore, (2016) as suitable for troglofauna, although there is relatively little sampling evidence that this is the case. They can also comprise alluvium and colluvium, from which troglofauna are increasingly often being collected (Biota, 2015). The deeper tertiary detritals consist of haematite conglomerate of silt and clay, with limited capacity to support troglofauna. The middle tertiary detrital layer consists of vuggy breccia, sand and calcrete that are suitable for troglofauna, together with lenses of clay that are not. The upper tertiary detrital layer consists of gravelly siltstone and siltstone that are likely to provide troglofauna habitat. Detritals are extensive in South Flank Valley, filling a broad valley north of Mount Robinson. Generally it is considered that subterranean species in detritals tend to be at least moderately widespread owing to more extensive habitat connectivity than in other subterranean environments (Bennelongia, 2019). One hundred and twenty six species of trogolofauna from 19 orders have been collected from the MS 1072 Development Envelope. Eighty-eight of these species have only been recorded from within the Development Envelope to date, although a number of these have a wide distribution within it. Most species occurred at very low abundance. The four singletons (species only ever recorded from one sample) recorded in the South Flank Impact Assessment Area will not be impacted by the Project as they occur outside of the groundwater mounding extent: · Prethopalpus sp. B15: recorded 1.2 km west of the western most extent of the Project mounding; · Prethopalpus julianneae: : recorded 2.2 km west of the western most extent of the Project mounding; · nr Andricophiloscia sp. B16: recorded 2.1 km east of the eastern most extent of the Project mounding; and · Parajapyidae ‘DPL024’: recorded 3.4 km east of the eastern most extent of the Project mounding; The seven other Troglofauna species recorded in the South Flank Impact Assessment Area will not be impacted by the Project: · Draculoides sp.B59-DNA: recorded approximately 9.5 km to the east of the easternmost extent of the proposed mounding area; · Prethopalpus maini: recorded approximately 0.6 km to the north and the furthest records are 3 km to the north west and 4.2 km to the east of the proposed mounding area. In addition all available habitat is outside of the proposed area of mounding; · Australoschendyla sp. B06: one record of this species is within the proposed mounding area. The other record is outside approximately 3.8 km to the east of the proposed mounding easternmost extent. · Chilenophilidae sp. B07: recorded approximately 3.8 km to the east of the easternmost extent of the proposed mounding area.
10 South Flank Surplus Water Scheme Works Approval Application Supporting Document · Japygidae sp. DPL007: recorded approximately 4 km to the east and 8.8 km to the north east of the easternmost extent of the proposed mounding area. · Parajapygidae sp. B25: recorded approximately 4 km to the east of the easternmost extent of the proposed mounding area. · Japygidae sp. DPL005: recorded 2.2 km west of the westernmost, and 1.5 km to the east of the easternmost edge of the proposed mounding area. 2.8.2. Stygofauna The considerable extent and habitat connectivity of the alluvial aquifers (and to a lesser extent the calcrete deposits) of the Tertiary detrital valley-fill successions in the Weeli Wolli and Coondewanna sub-catchments provide for easy dispersal of stygofauna species between areas of groundwater drawdown and surrounding aquifers (Bennelongia, 2019). A number of taxa (amphipods and isopods) occur both in the Mining Area C and in surrounding catchments. This suggests there are few, if any, physical barriers to restrict the wider ranges of species occurring in the cumulative groundwater drawdown areas (Bennelongia, 2016). Measurements taken during previous subterranean fauna survey demonstrate that the water table is relatively deep throughout the MS 1072 Development Envelope and surrounds, ranging from 26 to 127 metres below top of collar (mbtc) throughout South Flank and the groundwater is fresh, with conductivities at the water table rarely exceeding 1,000 µS cm-1 (Bennelongia, 2019). Sampling for stygofauna within the vicinity of MS 1072 has been considerable with at least 2,058 samples from 1,199 holes collected within 100 km by 100 km surrounding the Project Area (Bennelongia, 2019). Seven species of stygofauna have been recorded in the mounding area although six of these are known or considered to have ranges extending beyond the expected disturbance (Bennelongia 2019). The remaining species, the syncarid Bathynella sp. 2 (South Flank), is known from a single hole (SF3016R) east of the Project Area but within the mounding area. This occurrence of this species outside the mounding area cannot be confirmed based on current data (Bennelongia, 2019).
2.9. Contaminated Sites There are a number of contaminated sites within the boundary of Environmental Licence L7851/2002/6. None of these occur within the Project Area. The closest site is a suspected minor hydrocarbon spill associated with the now decommissioned South Flank Exploration Camp. This site is approximately 250m north of the north western edge of the Project Area. The proposed activities associated with this works approval will not impact on this site.

3.1. Corporate Level Plans and Procedures The management of the environmental aspects of BHP’s MAC operations are managed under the company’s AS/NZS ISO 14001:2016 certified Environmental Management System (EMS). The EMS describes the organisational structure, responsibilities, practices, processes and resources for implementing and maintaining environmental objectives at all BHP sites. Additionally, operational controls for environmental management for the Project are guided by BHP’s Charter values. The Charter Values outline a commitment to develop, implement and maintain management systems for sustainable development that drive continual improvement and set and achieve targets that promote efficient use of resources. In order to give effect to the Charter Values, a series of “Our Requirements” documents have been developed. BHP has also developed a Sustainable Development Policy for its Iron Ore operations. The Sustainable Development Policy outlines a commitment to setting objective and targets to achieve sustainable outcomes and to continually improve our performance. To support these documents BHP has an internal Project Environmental and Aboriginal Heritage Review (PEAHR) system. The purpose of the system is to manage implementation of environmental, Aboriginal heritage, land tenure and legal commitments prior to and during land disturbance. All ground disturbance activities will meet the requirements of the PEAHR system.
3.2. Premises Level Plans and Procedures At MAC all environmental management is currently governed by MS 1072, the associated Central Pilbara Water Resource Management Plan (Version 3.4) and Environmental Licence L7851/2002/6. All personnel carrying out works associated with the Project are required to comply with the Sustainable Development Policy, MS 1072, the Central Pilbara Water Resource Management Plan, Environmental Licence L7851/2002/6, the PEAHR system and any other relevant legislative and licensing requirements.
12 South Flank Surplus Water Scheme Works Approval Application Supporting Document 4. Proposed Amendments BHP is seeking a works approval to construct a new surplus water scheme at South Flank (the Project). The works approval application for the Project seeks to: · Construct a new managed aquifer recharge (MAR) scheme at South Flank consisting of nominally 10 reinjection bores (although additional reinjection bores may be required) to dispose of up to 12.76 GL/a of surplus mine dewater; and · Construct a surface water discharge scheme in Pebble Mouse Creek to dispose of up to 12.76 GL/a; 4.1.1. Project Description To manage surplus water from Mining Area C, BHP is proposing to construct a new surplus water scheme at South Flank. The Project (Attachment 2A) consists of: · Approximately 14 km of pipeline; · 1,100 kL balance tank; · A new MAR scheme at South Flank which will consist of: o Nominally 10 reinjection bores (Table 3; Attachment 2D). Note that additional reinjection bores may be required to meet the 12.76 GL/annum reinjection rate. If additional bores are required they will be constructed within the MAR Bore Construction Zone and as per the design specifications (Attachment 2D). DWER will be notified of any additional bores to be installed one month prior to construction. Following commissioning any new bores will be operated under Time Limited Operations (under the works approval) or the L7851/2002/6; o four regional monitoring bores (Table 3); and · A new surplus water discharge point into Pebble Mouse Creek (Attachment 2E). Based on the pump capacity, the system can operate at a maximum capacity of 12.76 GL/annum (a nominal 35 ML/day).

4.1.2. Environmental Impact Assessment and Associated Management Strategies BHP has assessed the potential emissions and discharges associated with the construction, commissioning and operation of the Project has been determined that the following potential impacts are relevant to this application: · Construction: o Noise and dust associated with the construction of the balance tank, pipeline, drill pads and Pebble Mouse Creek discharge Point; and o Discharge of groundwater from bore pump testing resulting in erosion. · Commissioning: o Groundwater mounding from reinjection resulting in a decline in vegetation health; o Groundwater mounding from reinjection resulting in a loss of subterranean fauna (troglofauna) habitat; and o Changes to groundwater quality from reinjection resulting in a loss of subterranean fauna (stygofauna) habitat; o Groundwater discharge resulting in erosion at the Pebble Mouse Creek discharge point; and o Discharge resulting in impacts to vegetation health downstream of the Pebble Mouse Creek discharge point · Operation: o Groundwater mounding from reinjection resulting in a decline in vegetation health; o Groundwater mounding from reinjection resulting in a loss of subterranean fauna (troglofauna) habitat; and o Changes to groundwater quality from reinjection resulting in a loss of subterranean fauna (stygofauna) habitat; o Groundwater discharge resulting in erosion at the Pebble Mouse Creek discharge point; o Discharge resulting in impacts to vegetation health downstream of the Pebble Mouse Creek discharge point; and o Groundwater discharge resulting in changes to surface water quality within Pebble Mouse Creek downstream of the discharge point. Note that the impacts of vegetation clearing have not been included in this risk assessment as all clearing will be undertaken in accordance with the approved MS 1072. Tables 5 to 7 provide a description of the proposed activities and the associated potential discharges/emissions, potential impacts, sensitive receptors, management measures, and residual risk ranking in accordance with Guidance Statement: Risk Assessments (DER, 2017) for the construction, commissioning and time limited operation of the Project.

5. Heritage The Land Access Unit is the internal group within BHP that manages Aboriginal heritage matters. The Land Access Unit is responsible for ensuring that BHP complies with the Aboriginal Heritage Act, 1972, and all other state and federal heritage legislation. All land disturbance activities are subject to ethnographic and archaeological surveys as part of an internal PEAHR. The PEAHR process ensures that all heritage sites in the vicinity of the Project Area are identified and avoided where practicable. The Project Area falls within the Banjima Native Title Claim (WC 11/6) and the Nyiyaparli Native Title Claim (WC 13/3). Archaeological and ethnographic surveys of the Project Area have been undertaken by BHP. Heritage sites have been mapped should any heritage site need to be disturbed as part of the Project BHP will obtain the relevant Section 18 approval.
6. Community Consultation BHP will continue to consult with DWER, and representatives of the Banjima and Nyiyaparli Native Title Claims.
7. Conclusion The proposed new surplus water scheme at South Flank is unlikely to introduce unacceptable emissions or discharges to land, water and air at the Mining Area C / Southern Flank Hub. The level of risk associated with each type of impact is believed to be low enough not to cause impacts to nearby sensitive receptors (human or environmental).

Note: For each class of shares issued by a proprietary company, ASIC records the details of the top twenty members of the class (based on shareholdings). The details of any other members holding the same number of shares as the twentieth ranked member will also be recorded by ASIC on the database. Where available, historical records show that a member has ceased to be ranked amongst the top twenty members. This may, but does not necessarily mean, that they have ceased to be a member of the company.

Note: For each class of shares issued by a proprietary company, ASIC records the details of the top twenty members of the class (based on shareholdings). The details of any other members holding the same number of shares as the twentieth ranked member will also be recorded by ASIC on the database. Where available, historical records show that a member has ceased to be ranked amongst the top twenty members. This may, but does not necessarily mean, that they have ceased to be a member of the company.
