Western Australia has the longest coastline of any state or territory in Australia, at 12,889 km (20,781 km including islands). It is a significant portion of the coastline of Australia, which is 35,877 km (59,736 km including islands). The earliest full charting of the coastline occurred during exploration in the late eighteenth and early nineteenth centuries. The coastline has some features or organisms that are found on the entire length, while some others are specific to particular coastal regions. Western Australia has some of the most remote and harsh coastline in the world. The coast sweeps in a great semicircle, facing south on the Southern Ocean, west and northwest on the Indian Ocean, and north on the Timor Sea. It was one of the last states to be lit, with most lights dating from the turn of the 20th Century. This lab cache highlights some of the lighthouses along Western Australia’s coastline, the history and the importance of navigating our dangerous coastline.
