Great White Shark
Carcharodon carcharias
Encountered in Australia from a cage at the Neptune Islands — wildlife tourism rather than scuba diving.
The Neptune Islands off Port Lincoln are the only place in Australia where great white shark cage experiences operate, and they exist because of the large New Zealand fur seal colony there.
This is wildlife tourism rather than certified scuba diving. The standard experience is a surface cage using surface-supplied air or simply snorkelling gear, and no certification is required. Some operators offer deeper cage options for certified divers.
Treating it as a dive site in the ordinary sense is a category error, which is why this directory classifies cage operators separately from scuba centres.

In-water etiquette
Great White Shark is vulnerable. How divers behave around it genuinely matters.
- Keep all limbs inside the cage — this is the entire rule and it is not negotiable.
- Follow the operator's briefing precisely.
- Choose operators whose attractant practices you are comfortable with; methods and regulation differ.
