About Neptune Islands

Neptune Islands are a remote offshore shark-cage destination in South Australia, best known for great white encounters rather than casual reef diving. The site suits guided boat trips and carefully timed cage dives because the islands are exposed, the access is restricted, and the whole experience depends on weather windows and local operator planning.
