Things to do · Destination Guide
Temperate sponge gardens, current-swept walls, historic wrecks and seal-rich bay snorkeling within reach of Melbourne.
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Port Phillip Bay rewards cool-water divers with protected sponge gardens, dramatic Heads walls, pier macro life and the ex-HMAS Canberra wreck just outside the entrance. Base around Queenscliff for organized boats or Rye for selected shore entries. Current-swept wall and wreck routes require qualifications, tide timing and boat judgment rather than tropical-style casual diving. Parks Victoria; ex-HMAS Canberra guidance.
Pope's Eye
Protected ring offers calmer shallows than the outer structure; suitable site selection can work for novice divers with an appropriate guide.
Lonsdale Wall and the Rip
Temperate sponge gardens, overhangs and swift, tide-dependent currents; specialist local charter planning.
Rye Pier
Pylon life and a possible winter giant spider-crab aggregation; follow pier use restrictions and current local signage.
Portsea Hole
A distinctive deep wall up to 30 m; only Advanced Open Water level or equivalent, never a snorkeling site.
ex-HMAS Canberra
Artificial reef and large warship wreck outside the bay; inspect weather, depth, current, entry hazards and certification.
