Some of the places i have dived recently:
Heron Island:
Wheeler Reef:
Magnetic Island:
Orpheus Island:
Davis Reef:
S.S. Yongala:
I turned tropical in 2005 when i went to the GBR to study marine biology, hence all the reefs.
I still love diving and snorkelling in temperate waters though, it's how i grew up.
Of my 21 years, i have spent 8 years diving and ~15 snorkelling so far, with many, many more to come!
Incidentally i'm Padi certified.
