Business - provider partnerships numbers and growth In the past business - provider partnerships for trainiug in the water sector have been adhocand there has been little national coordination. Moreover, at the start of this project there were or~lytwo examples of a business - provider partnership for e-learning in the water industry in Australia. These were: a relationship between Wide Bay Water and Sunwater for water worker training and a preliminary arrangement between Wide Bay TAFE and Wide Bay Water to provide on-line training services to other Councils. The collaborative model of industry sector long-term funding has already (in the first three months) resulted in an increase in the number of relationships through two mechanisms. These are: new partnerships as a direct result of the project, and negotiation of partnerships with other RTOs through leverage provided by the project. Two new partnerships have arisen as a result of the industry funding.

  • Sunwater Dams Sunwater Makes a Significant Contribution to the Rural, Industrial, Energy, Mining and Urban Development of Queensland by Providing Water Solutions
    SunWater Dams SunWater makes a significant contribution to the rural, industrial, energy, mining and urban development of Queensland by providing water solutions. Over the past 80 years, SunWater has designed and managed the construction of 30 of Queensland’s dams, 82 weirs and barrages, 39 reservoirs and balancing storages and rural and bulk water infrastructure systems. Currently, SunWater owns and manages 19 dams in Queensland and each dam has been strategically built in existing river, stream or creek locations to serve the needs of the region. A dam is a critical component of a water supply scheme which can be made up of weirs and barrages, pumping stations, pipelines and channels, and drains. The overall scheme is designed to supply water for various purposes including town water supply, irrigation, electricity production, industrial i.e. power stations, mines, stock and groundwater supply. Water Supply Scheme Pipeline Industrial & Mining Dam Drain Pumping Station Channel Legend Balancing Storage SunWater Infrastructure Purpose of Water Supply Weir Irrigation Town Barrage Water Supply Dam Types The type of dam is defined by how the dam wall was constructed. Depending on the surrounding environment, SunWater dams can be described as one or more Scheme of the following: Pipeline Cania Dam Boondooma Dam Wuruma Dam Paradise Dam Julius Dam EMBANKMENT CONCRETE FACED MASS CONCRETE ROLLER COMPACTED MULTIPLE ARCH Industrial & Mining ROCKFILL GRAVITY CONCRETE GRAVITY CONCRETE Constructed as an Constructed as an BUTTRESS embankment of well Constructed using a Constructed in horizontal embankment of compacted Constructed as concrete compacted clay (earthfill) some large volume of layers of dryer than normal free-draining granular earth horizontal arches supported with rock on the faces (rockfill).

    Queensland Parliamentary Debates [Hansard] Legislative Assembly THURSDAY, 28 MARCH 1968 Electronic reproduction of original hardcopy 2588 Questions [ASSEMBLY] Questions to the Leader of the Opposition marked "The Premier's Department has no jurisdiction over such private companies or matter, and the question also seeks an expression of opinion." I remind hon. members that questions should relate only to matters for which the Minister is responsible. In this case the MinLter cannot in any way be held respon­ sible; it is purely a private matter between the management and the employee. Mr. HOUSTON: Thank you, Mr. Speaker. Mr. R. JONES (Cairns): Mr. Speaker, in view of your ruling, I notice that one of my questions has been ruled off the Business Paper. It was directed to the Minister for Transport, who, I believe. is responsible for intrastate air services in the State of Queens­ land. Mr. SPEAKER: Order! I can explain that very briefly. It is a Commonwealth matter. Mr. R. JONES: Intrastate? Mr. SPEAKER: Order! I remind the hon. member that it is not in order to debate the disallowance of a question. Mr. R. JONES: Mr. Speaker, this is not interstate, it is intrastate. He is responsible. THURSDAY, 28 MARCH, 1968 Mr. SPEAKER: Order!

  • Queensland Geological Framework
    Geological framework (Compiled by I.W. Withnall & L.C. Cranfield) The geological framework outlined here provides a basic overview of the geology of Queensland and draws particularly on work completed by Geoscience Australia and the Geological Survey of Queensland. Queensland contains mineralisation in rocks as old as Proterozoic (~1880Ma) and in Holocene sediments, with world-class mineral deposits as diverse as Proterozoic sediment-hosted base metals and Holocene age dune silica sand. Potential exists for significant mineral discoveries in a range of deposit styles, particularly from exploration under Mesozoic age shallow sedimentary cover fringing prospective older terranes. The geology of Queensland is divided into three main structural divisions: the Proterozoic North Australian Craton in the north-west and north, the Paleozoic–Mesozoic Tasman Orogen (including the intracratonic Permian to Triassic Bowen and Galilee Basins) in the east, and overlapping Mesozoic rocks of the Great Australian Basin (Figure 1). The structural framework of Queensland has recently been revised in conjunction with production of a new 1:2 million-scale geological map of Queensland (Geological Survey of Queensland, 2012), and also the volume on the geology of Queensland (Withnall & others, 2013). In some cases the divisions have been renamed. Because updating of records in the Mineral Occurrence database—and therefore the data sheets that accompany this product—has not been completed, the old nomenclature as shown in Figure 1 is retained here, but the changes are indicated in the discussion below. North Australian Craton Proterozoic rocks crop out in north-west Queensland in the Mount Isa Province as well as the McArthur and South Nicholson Basins and in the north as the Etheridge Province in the Georgetown, Yambo and Coen Inliers and Savannah Province in the Coen Inlier.
