of John Stanley Beard, all of which are based on biogeography. Other natural regionalisations included the drainage basins and catchments of river systems, and highly specialised regionalisations dealing with such matters as geology and soil systems. Administrative regionalisations include Landcare Districts and the Department of Agriculture's "Land-use Zones". However the Department of Agriculture publications – Technical Bulletins – usually titled An inventory and condition report/survey... of a particular region are very specifically focused upon land systems that are based on natural features. Land tenure Western Australia is divided into approximately 90 land districts for cadastral purposes. There are five land divisions in Western Australia, as specified in Schedule 1 of the Land Administration Act 1997. Eastern Land Division Eucla Land Division Kimberley Land Division North-West Land Division South-West Land Division Wine regions Western Australia covers the western third of the continent, although the winemaking regions are almost entirely situated in the south-western tip of the state. It has nine regions, and five nominated subregions for wine under the geographical indications legislation as determined by the Australian Wine and Brandy Corporation. Wine regions include: Greater Perth Perth Hills Peel Swan District South Western Australia Blackwood Valley Geographe Great Southern Albany Denmark Frankland River Mount Barker Porongurup Manjimup Margaret River Pemberton Coastal regions Western Australia has the longest coastline of any state in Australia, at 10,194 km. The regions can be determined by the underlying geology, and in the case of the Bureau of Meteorology – features such as points and capes are useful indicators of coastal water forecasts. Landgate publishes touring maps that include coastal zones including: Batavia Coast (incorporating the area of Dongara, Geraldton, and Kalbarri) Gascoyne Coast (Carnarvon, Coral Bay, Denham, Exmouth and the Coral Coast) Coral Coast (at the northern end of the Gascoyne Coast) Turquoise Coast north of sunset Coast and south of Batavia coast Sunset Coast (Perth Metropolitan beachside suburbs from Cottesloe to Yanchep) Census and Australian Bureau of Statistics For the purposes of statistical geography, the Australian Bureau of Statistics uses the Australian Standard Geographical Classification, a hierarchical regionalisation that divides Western Australia into statistical divisions, then statistical subdivisions, statistical local areas, and finally, census collection districts. Statistical divisions include: SD 505 – Perth SD 510 – South West SD 515 – Lower Great Southern SD 520 – Upper Great Southern SD 525 – Midlands SD 530 – South Eastern SD 535 – Central SD
