Coastal regions of Western Australia
Western Australia has the longest coastline of any state in Australia, at 10,194 km [1] or 12,889 km.[2]
Integrated Marine and Coastal Regionalisation of Australia
The IMCRA has offshore regions delineated in a systematic appraisal of ecology and geography [3]
Coastal regions used in weather reports
Standard Bureau of Meteorology reports include the following reference points for coastal weather reports:[4] -
- WA/NT border (or Wyndham) to Kuri Bay:
- Kuri Bay to Wallal: (Kimberley land region)
- Wallal to Cape Preston: (Pilbara land region)
- Cape Preston to North West Cape: (Pilbara land region)
- Northwest Cape to Carnarvon: (Gascoyne land region)
- Carnarvon to Kalbarri: (Gascoyne land region)
- Kalbarri to Jurien Bay: (Central west land region)
- Jurien Bay to Mandurah: (Lower west land region)
- Mandurah to Cape Leeuwin: (South west land region)
- Cape Leeuwin to Bremer Bay: (South west and South coastal land regions)
- Bremer Bay to Israelite Bay: (Southeast coastal land region)
- Israelite Bay to SA Border: (Eucla land region)
General coastal regions
There are groupings for wider regions that are based very close to the land regions, one made in the 1980s [5] - has 8 coastal regions, while the 2003 Coastal Planning and Management Manual has five regions with component sections [6]
- Kimberley Coast - Northern Territory / Western Australia border to Broome (2003 manual 'Figure 2-2 Pilbara Kimberley Region')
- Canning - Broome to Port Hedland (Cape Keraudren - east of the De Grey River delta in the 2003 manual)
- Pilbara - Port Hedland to Onslow
- Coral Coast or Gascoyne region - Onslow to Kalbarri (Shark Bay in the 2003 manual)
- Kalbarri to Cape Naturaliste - which includes - the 'Central West' also known as the 'Turquoise Coast' and another further south known at the Sunset Coast
- South West Capes - Cape Naturaliste to Cape Leeuwin (to Albany in the 2003 manual)
- Cape Leeuwin to Israelite Bay South Coast - incorporates the coastal region between Cape Leeuwin and Windy Harbour, usually considered part of the south west;
- South Coast Region or the South East - Israelite Bay (Albany in the 2003 manual) to the Western Australia / South Australian Border (Eucla)
Ports, settlements and towns
Fisheries bioregions
Under the Fish Resources Management Act 1994 there are four main regions on the Western Australian coast.[7]
- North Coast (Pilbara/Kimberley) from the Western Australian and Northern Territory border to 114° 50' E 21° 46' S, just west of the mouth of the Ashburton River Mouth.
- Gascoyne Coast[8] from 114° 50' E 21° 46' S, just west of the mouth of the Ashburton River Mouth to 27° S - about half way between Kalbarri and Denham.
- West Coast from 27° S - about half way between Kalbarri and Denham south to 115 ° 30' E - Black Point east of Cape Leeuwin.
- South Coast from 115 ° 30' E - Black Point east of Cape Leeuwin, to the South Australian Border
