First, a disclaimer:
Our Australian diving is exclusively East Cost based. Not necessarily because it's better (indeed, there are places such as Ningaloo that we're dying to visit), but as is often the way with tourism and Australia, it often ends up far cheaper and easier to visit other countries than go west.
That said, there are many great dives sites in eastern Australia, including:
- Sydney - our home turf
- Neptune Islands - sharks shark sharks!
- Great Barrier Reef - many wonderful sites within the largest living organism on earth (fact), including
- the SS Yongala - oasis of life on the sandy sea bed.
