One of our dive buddies just got back from that trip. Nice shots of the Great Whites.
The octopus is Common Sydney Octopus. Mark Norman states in A Guide to Squid, Cuttlefish Octopuses of Australia "It is easily identified in the field by it's white eye" The orange arms are also ID points. We see a fair number of these. They can get quite large and are good at colour changes and large papillae which they raise to produce a spiked appearance.
