Being on a sandy floor in 27 metres of water, sitting bolt upright the HMAS Brisbane has 12 to 15 metres of water over her forward decks and 18 metres over her stern. Consistently good water clarity and minimal swell makes for great diving.

Water temperatures range from 17C in winter to a summer high of 27C. Visibility averages around 15 metres but up to 20 metres or more is not uncommon.

Local inhabitants include a large bull ray, angler fish, lion fish, blennies, nudibranchs, sea hares, squid and small schools of juvinile snapper. Other visitors include a shovelled nose ray, greasy cod and eagle rays. An octopus has made a home in a pyrotechnic tube on deck!
