Recherche Archipelago
More than a hundred granite islands off Esperance, with sea lions and extraordinary clarity.
The Recherche Archipelago spreads more than a hundred granite islands offshore from Esperance, at the edge of the Great Australian Bight.
The water here can be extraordinarily clear, and the granite terrain combined with Australian sea lion colonies makes for diving unlike anywhere else in Western Australia.
It is remote and weather-dependent — when conditions align it is exceptional, and when they do not, trips do not run.
