Western Australia has the longest coastline of any state or territory in Australia, at 10,194 km[1] or 12,889 km (20,781 km including islands).[2][a] It is a significant portion of the coastline of Australia, which is 35,877 km (59,736 km including islands).[2]

The earliest full charting of the coastline occurred during exploration in the late eighteenth and early nineteenth centuries.[3]

The coastline has some features or organisms that are found on the entire length,[4] while some others are specific to particular coastal regions.[5][6]

Various government map posters have been created over time, which have examples of coastal form, or types of coast such as the 1984 map with photos.[7]

Integrated Marine and Coastal Regionalisation of Australia (IMCRA)[edit]

The IMCRA has offshore regions delineated in a systematic appraisal of ecology and geography.[8]

Coastal regions used in weather reports[edit]

Standard Bureau of Meteorology reports include the following reference points for coastal weather reports:[9]

  • North Kimberley Coast: WA/NT border (or 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[edit]

There are groupings for wider regions that are based very close to the land regions; one made in the 1980s[10] has 8 coastal regions, while the 2003 Coastal Planning and Management Manual has five regions with component sections:[11]

  • 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)

Ports, settlements and towns[edit]

Fisheries bioregions[edit]

Under the Fish Resources Management Act 1994 there are four main regions on the Western Australian coast.[12]

Features[edit]

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:

Gulfs[edit]

Sounds[edit]

Specifically referring to Sound (geography)

Archipelagoes and island groups[edit]

Aquatic flora[edit]

The Western Australian coastline has the greatest diversity of seagrasses in the world, and the meadows they form are among the largest on earth.[13]

Notes[edit]

  1. ^ The length of a coastline may vary significantly depending on how it is measured.
  2. ^ Not to be confused with the tourist coast region which might have slightly different start and finish points from the fisheries designated coast
