Australian Great White Shark cage diving is the closest you can safely get to seeing these apex predators in their natural environment. It is a unique experience and one that will allow you to fully appreciate these incredible creatures.
In Australia it is only allowed at the Neptune Islands in the state of South Australia, a location which is one of the three main ones globally where you can actually be in the water safely with Great White Sharks – the other two are Gansbaai in South Africa and Guadalupe Island in Baja Mexico.
Great White Sharks inhabit all the temperate marine waters of the world but given their relatively small & declining global population, and the sheer size of the ocean, the chances of actually seeing one is extremely small. In Australia we are fortunate to have one of the three best places in the world to see Great Whites – the Neptune Islands in South Australia, where the Spencer Gulf meets the Great Australian Bight.
Australian Great White Shark Cage Diving – Port Lincoln
Port Lincoln in the Spencer Gulf is Australia’s tuna fishing capital and the place to start your journey to see the Great White Shark face to face.
It is a short 40 minute flight across the Spencer Gulf from Adelaide, the capital of South Australia, and as you fly in you will see a number of rings floating in the sea.
These are the tuna pens where the juvenile tuna, caught in the Southern Ocean using a technique developed in Port Lincoln and now generally adopted globally, are kept while they are force fed to fatten them up before being harvested and shipped to Japan.
It is the tuna pens and their rich harvest that make Port Lincoln probably the wealthiest per capita town in Australia.
But that wealth is earned and if you want to understand how, check out the National Geographic documentary Tuna Cowboys that is now available on YouTube!
Once the tuna is harvested it is cleaned, tagged and either put into deep freeze pending the arrival of the mother ship that transports it back to Japan, or it is chilled and flown there (usually on the evening it has been harvested) where it’s freshness brings a significant premium.
Either way the tuna ends up at the massive Tsukiji Fish Market in Tokyo…
Australian Great White Shark Cage Diving – Neptune Islands
The Neptune Islands are 15 nautical miles and between 2.5 to 4 hours from Port Lincoln, depending on the vessel you are on, and the main location for Australian Great White Shark cage diving.
The reason is very simple – there is a large seal colony to be found on the western island of North Neptune, and seals are the Great White Shark’s high fat food of choice.
The big positive about cage diving at the Neptune Islands is the clear blue water from the Southern Ocean and the Great Australian Bight which provide a great backdrop to see and photograph the Great White.
