The beautiful Neptune Islands are a Conservation Park consisting of 2 island groups (North and South) and are located at the mouth of the Spencer Gulf, here in South Australia.
Both of these island groups are home to large breeding colonies of the protected New Zealand fur seals (Arctocephalus forsteri) which is of course why the great white sharks visit. The smaller North East island also has a very small number of breeding Australian sea lions (Neophoca cinerea.) These beautiful sea lions are listed as both 'rare' and 'endangered'. See Sharks and Seals for more information.
Where we anchor each day is dependent on the weather but usually in winter this is nicely tucked up in 'The Main Bay' of North Neptunes West and in summer is usually north of North Neptunes East and in 'Action Bay'.
The sea surface temperature around the islands ranges from 14-22°C (57-72°F) and the water visibility of over 20m can be experienced in our surface cage and ocean floor diving. We will always anchor taking weather, diving and best place for sharks into consideration.
The depths we ocean floor cage dive in can vary depending on where we are anchored but average around 18m, so to take part in this world exclusive experience a basic PADI open water certificate or equivalent is all that is needed. Remember no dive certificate is needed for the surface cage diving!
Depths further around the islands are 30-50m.
Each expedition inlcudes a tour (weather dependent) around the islands in our tender boat to get a better look at the amazing array of species that live there. Access on to the islands is not permitted.
