Geraldton & Abrolhos Islands · Western Australia
Houtman Abrolhos Islands
122 islands 60 km offshore, where coral grows alongside kelp and the Batavia was lost in 1629.
The Houtman Abrolhos Islands are a chain of 122 islands roughly 60 kilometres off Geraldton, and among the most ecologically unusual dive destinations in Australia.
The Leeuwin Current carries warm water south along the coast, allowing coral to grow here alongside temperate kelp — an overlap that occurs in very few places worldwide.
The wreck of the Batavia, lost in 1629, is among the most historically significant shipwrecks in Australian waters, and the islands carry the archaeology to match.
