Rat Island, Protected island in Easter Group of Houtman Abrolhos, Western Australia.
Rat Island is a small island in the Houtman Abrolhos Group off the Western Australian coast, characterized by limestone formations and low vegetation. The terrain appears rocky and sparse, with exposed stone formations and minimal tree cover throughout.
In the early 1900s, a railway line was built to transport guano and limestone from the island to the jetty. This infrastructure supported extraction activities that shaped the island's economy during that period.
The island serves as a research station where scientists study seabird populations and their breeding habits. Visitors walking across the terrain can observe the birds and understand how the island functions as a living laboratory.
Access to the island is via the Abrolhos Rat Island Airport, which is the primary transportation hub for the area. Visitors should be prepared for remote conditions with limited facilities and amenities on the island.
The stone railway jetty still stands on the island as a remnant of early resource extraction activities. This structure offers visitors a tangible connection to the industrial past that once shaped island operations.
