Diving in Geraldton & Abrolhos Islands
The Houtman Abrolhos, 60 km off Geraldton, are 122 islands with coral reefs, the Batavia (1629) wreck site and huge crayfish populations in water that mixes tropical and temperate species. Geraldton itself has the Point Moore reefs and the SS Sunbeam and other wrecks.
