The June 2007 Northern Pastoral Memo has something interesting in it for everyone. News of dwindling donkey populations around Halls Creek will be sure to bring a smile to many faces, AQIS has kindly provided information on export numbers from northern ports in 2007 and the Bush Nurse has made a return with some information on nasty viruses carried by mosquitoes. The feature article for the June Pastoral Memo is a summary of an ‘industry initiative to improve young breeder performance in the Pilbara and Kimberley of WA’. It is great to see some beef research happening across the Kimberley and Pilbara. Although the ‘young breeder project’ for short is not planned to finish until 2009, some best bet management practices to improve young breeder herd productivity have already been identified. The Pastoral Memo also has a new section for all readers interested in cattle markets locally, interstate and abroad. Information for this section had been kindly supplied by Meat and Livestock Australia. Happy reading Matthew Fletcher http://www.agric.wa.gov.au 3 PASTORAL MEMO – NORTHERN PASTORAL REGION JUNE 2007 KIMBERLEY AND PILBARA ‘WET’ SEASON ROUND-UP By Matthew Fletcher, Kununurra and Peter Smith, Karratha Kimberley 2006/07 wet season - summary and 2007/08 planning At the completion of the 2006/07 wet season a majority of stations in the Kimberley had received average to above average rainfall (see page 2). February was an extremely lean month for rainfall across the Kimberley and Pilbara and will be remembered as one of the lowest on record, with a majority of leases receiving less than 10 mm of rain for the month. It was not until mid March when a monsoonal trough combined with the passing of the MJO (Madden-Julian Oscillation) and dumped heavy falls of rain across the Kimberley, improving rainfall totals and prospects for the 2006/07 season. It is interesting to compare levels of Total Standing Dry Matter (TSDM) at the completion of the 2006 and 2007 wet seasons (see website at the end of this article). There appears to be less TSDM available to utilise for stock going into 2007 than there was in 2006. TSDM is the total amount of grasses, herbs and small seedlings growing in the pasture layer. What does this imply for rangeland management? At the first muster there is an opportunity to align numbers of stock going back into paddocks with the amount of useful forage available. It is important to remember that cattle do not graze all grasses evenly. Cattle preferentially graze desirable grasses, therefore stock numbers need to be aligned with the amount of desirable forage available to minimise overgrazing of these perennial grasses. Pastoralists aligning stocking rates with the amount of desirable forage grown, provide an opportunity for an increase in desirable perennial grasses on their lease and better animal performance and potentially higher stock numbers in the future. Ultimately this increased productivity from desirable grasses will improve a station’s bottom line. If you would like to know more about desirable grasses on your lease in the Kimberley please give me a call at Kununurra on (08) 9166 4019. Pilbara 2006/07 season Some areas of the east and central Pilbara received scattered storms before Christmas and while these resulted in some useful pasture response in a few isolated areas, they often produced some serious fires burning large areas of country. One fire in the Millstream area burnt out a large area of good country in the Fortesque Valley. The speed of this fire rendered control measures largely ineffective. As with the Kimberley season, the season in the Pilbara was late with little useful rain until the cyclone influences of George and Jacob in early March and Kara in late March. All of these influences crossed the coast west of Port Hedland and resulted in good falls of rain in the east and central Pilbara. The west Pilbara, west of Karratha, received some useful falls from scattered storms but no general rain. An influence in early May produced some useful falls in the area between Nanutarra and Carnarvon and to the east, but again the west Pilbara generally missed out. The effect of these rainfall events is reflected in the TSDM estimates for 2007 (see website below). While the likelihood of useful winter rain is better in the west Pilbara and further south, good falls will be required to produce any sort of a body feed. Smaller falls are likely to improve the quality of feed on offer but do little to improve the quantity of feed available.

Larissa: I think a lot of Australians don't know that history because I know I definitely didn't until I came up into the Kimberley and then you're exposed to it. Um, and - 'cause living in a city like you - you do - you - you end up in your little bubble and your - your life and this is how things are and - and you don't step outside of that box until you either travel and then you get a little taste of it or you - you go somewhere and experience it. Cameo: Today we travel to one of Australia’s most iconic and remote regions. Located in the North-West corner of Australia, the Kimberley is famous for its spectacular scenery. Rocky outcrops, cascading waterfalls and rare plants and animals draw many visitors each year. These dramatic landscapes have also been the site of brutal and traumatic histories for Aboriginal people at the hands of White settlers. In 2004 Aboriginal people had their underlying rights to land recognized over a large swathe of the Kimberley. This recognition came under Australia’s Native Title Act, which is often touted as delivering direct benefit to Indigenous people.

  • LEGISLATIVE COUNCIL Question on Notice
    LEGISLATIVE COUNCIL Question On Notice Wednesday, 10 October 2018 1687. Hon Robin Chapple to the Minister for Environment representing the Minister for Lands In relation to the Govemment's support for carbon sequestration proj ects on Westem Australia's pastoral leases, I ask: (a) which carbon sequestration project methods approved under the Federal Government's Emissions Reduction Fund fall within the definition of 'pastoral purposes' as outlined under Westem Australia's Land Administration Act 1997; (b) when does the Govemment expect it will be in a position to start providing eligible interest holder consent for carbon sequestration projects on pastoral leases; (c) is the Govemment considering providing consent for all carbon sequestration projects that have been provisionally registered with the Emissions Reduction Fund, or only those projects that have been successful in securing contracts to supply carbon credits to tile Federal Govemment; (d) is the Govemment aware that by 1 July 2019, over 20 per cent of Westem Australian pastoral leases will have te=s that are less than 25 years, and that consequently under current legislation, pastoralists and other leaseholders will be unable to register a carbon sequestration proj ect because they require tenure of at least 25 years duration; (e) what are the names of the pastoral leases and the regions in which they are situated that, at 1 July 2019, will have 25 years or less of their terms left to run; (f) of the leases listed in (e), how many are Aboriginal-owned; (g) will the Govemment provide for leaseholders to undertake carbon sequestration proj ects of a duration of 100 years which is the intemationally accepted and compliant standard; and (h) if yes to (g), what tenure will provide for such projects? Answer (a) To date, the State of West em Australia has only formally considered the approved Human-Induced Regeneration of a Pel111anent Even-Aged Native Forest method, in te=s of consistency with 'pastoral purposes' as defmed within Part 7 of the Land Administration Act 1997.

    Mingalkala Layout Plan 1 Background Report September 2005 Date endorsed by WAPC Amendments Amendment 1 - April 2013 Amendment 2 - August 2018 Amendment 3 - July 2020 MINGALKALA LAYOUT PLAN 1 Layout Plan 1 (LP1) was prepared during 2005 by Sinclair Knight Merz. LP1 has been endorsed by the resident community (25 July 2005), the Shire of Halls Creek (25 August 2005) and the Western Australian Planning Commission (WAPC) (27 September 2005). During the period April 2013 until August 2018 the WAPC endorsed 2 amendments to LP1. The endorsed amendments are listed in part 7 of this report. Both amendments were map-set changes, with no changes made to the background report. Consequently, the background report has become out-of-date, and in June 2020 it was updated as part of Amendment 3. The Amendment 3 background report update sought to keep all relevant information, while removing and replacing out-of-date references and data. All temporal references in the background report refer to the original date of preparation, unless otherwise specified. As part of the machinery of government (MOG) process, a new department incorporating the portfolios of Planning, Lands, Heritage and Aboriginal lands and heritage was established on 1st of July 2017 with a new department title, Department of Planning, Lands and Heritage. Since the majority of this report was finalised before this occurrence, the Department of Planning, Lands and Heritage will be referred to throughout the document.

  • Ockham's Razor
    The Journal of the European Association for Studies of Australia, Vol.4 No.1, 2013. Reading Coolibah’s Story: As told by Coolibah to John Boulton John Boulton Copyright © John Boulton 2013. This text may be archived and redistributed both in electronic form and in hard copy, provided that the author and journal are properly cited and no fee is charged. Abstract: This paper describes selected key events in the life of Coolibah, a retired Gurindji stockman, through his non-Aboriginal friend John Boulton. Coolibah made John “a close friend of the same age”, referred to specifically as tjimerra in Gooniyandi language (the language that he has become most familiar with since being removed from his family as a small child). This classifactory kin relationship makes it possible for John Boulton to tell Coolibah’s story. This article is situated within the tradition of oral histories of the lives of Aboriginal people at the colonial frontier. It is also within a tradition of friendships between Aboriginal and non-Aboriginal, including European, people, often anthropologists and other professionals with a deep commitment to that world. In this article, Boulton uses the events of Coolibah’s life and that of his family and kin as a departure point to discuss the impact of history on the health of the people. Coolibah’s life is viewed through the lens of structural violence whereby the causal factors for the gap in health outcomes have been laid down. This article provides the theoretical framework to understand the extent of psychic, emotional and physical harm perpetrated on generations of Aboriginal people from the violent collision of the two worlds on the Australian frontier.
