Coastal regions of Western Australia
Commonly used Bureau of Meteorology coastal landmarks
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 (IMCRA)
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]
- North Kimberley Coast - WA/NT border (or Wyndham) to Kuri Bay
- West Kimberley Coast - Kuri Bay to Wallal (Kimberley land region)
- Pilbara Coast East - Wallal Downs to Cape Preston (Pilbara land region)
- Pilbara Coast West - Cape Preston to North West Cape (Pilbara land region)
- Ningaloo Coast - Northwest Cape to Carnarvon (Gascoyne land region)
- Gascoyne Coast - north of Carnarvon to Kalbarri (Gascoyne land region)
- Geraldton Coast - north of Kalbarri to Jurien Bay (Central west land region)
- Lancelin Coast - Jurien Bay to Two Rocks (Lower west land region)
- Perth Local Waters - Two Rocks to Dawesville (Lower west land region and/or Perth Metropolitan region)
- Perth Coast - west of Rottnest and Perth Local Waters (same limits of Two Rocks and Dawesville)
- Bunbury Geographe Coast - Dawesville to Busselton, (part lower west and part south west land region)
- Leeuwin Coast - Busselton to west of Denmark (South west land region)
- Albany Coast - west of Denmark to Bremer Bay (south coast coastal land region)
- Esperance Coast - Bremer Bay to Israelite Bay (Southeast coastal land region)
- Eucla Coast - 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 Coast - Port Hedland to Onslow
- Coral Coast or Gascoyne region - Onslow to Kalbarri (Shark Bay in the 2003 manual)
- Kalbarri to Cape Naturaliste - which includes, Batavia Coast, 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)
- South Coast - Cape Leeuwin to Israelite Bay - 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)

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
Features
The coastal regions include a range of beaches, cliffs, and coastline features that are dependent upon the underlying geology; the geological provinces have direct relationship to the coastal forms:
- Eucla Basin - Eucla - Israelite Bay - Limestone
- Yilgarn Craton - Point Malcolm - Cape Arid and Point Hood to Point D'Entrecasteaux
- Bremer Basin - Israelite Bay - Point D'Entrecasteaux
- Perth Basin - Augusta - Murchison River
- Carnarvon Basin - Murchison River - Cape Preston
- Pilbara craton - Cape Preston - Port Hedland
- Canning Basin - Port Hedland - King Sound
- Kimberley Basin - Kimberley Coast
- Bonaparte Basin - Cambridge Gulf
