Eighty Mile Beach : Western Australia
Eighty Mile Beach lies along the north-west coast of Western Australia about half-way between the towns of Broome and Port Hedland.
At 220 kilometres (140 mi) in length, it forms the coastline where the Great Sandy Desert (Top) approaches the Indian Ocean. It consists of sand with a high proportion of shelly material, and experiences a very large tidal range with an amplitude of up to 9 meters.
The adjoining tidal mudflats vary from 1-5 km in width. On the landward side it is bordered by dunes, a narrow floodplain and, further inland, by a strip of pindan woodland or shrubland.
The Great Sandy Desert contains large ergs, often consisting of longitudinal dunes. It is the second largest desert in Australia after the Great Victoria Desert.
The Great Northern Highway (Bottom to Top Left) travels through remote areas of the state, and is the only sealed road link between the Northern Territory and northern Western Australia.
With a length of almost 3,200 kilometres (2,000 mi), it is the longest highway in Australia, with the majority included as part of the Perth Darwin National Highway.
The highway was created in 1944 from existing roads in the Wheatbelt and a series of tracks through remote pastoral areas. However, it was a hazardous route that could be dusty in the dry season, and boggy or washed away in the wet season. Some sections were effectively impassable sand, while others contained limestone outcrops.
The two-lane sealed road between Halls Creek and Wyndham was also completed in 1978. It involved the construction of 21 bridges, and extensive earthworks designed to blend the road into the terrain. With the opening of this section, tourist traffic escalated to
Cape Keraudren and Eighty Mile Beach.
