Meet the site
Buckleys Cave is the hollow in the cliff below the Point Lonsdale lighthouse where William Buckley, the convict who escaped from the short-lived Sorrento settlement in 1803, is said to have sheltered during the thirty-two years he lived with the Wadawurrung people before walking into John Batman's camp in 1835. The reef below the cave, on the Bass Strait side of the point, is the most exposed and most demanding shore dive on the Bellarine and one of the few places a diver can enter the Rip's edge from the rocks. The ground is limestone and calcarenite reef running from the platform edge at 2 m out to about 10 m, with a distinctive outcrop known as Mushroom Rock and a deep gutter, the shark gutter, cutting through it, all of it scoured by the tide and swell into ledges and holes. The growth is fully oceanic: kelp and crayweed on the tops, sponges, ascidians and jewel anemones under the ledges, and fish that include blue-throat wrasse, magpie perch, old wives, sweep, boarfish, leatherjackets, scalyfin, zebrafish, southern rock lobster in the holes, Port Jackson sharks in the gutter (hence the name) and fur seals from the Heads. The reef is also a graveyard: the Glaneuse (1886) lies 150 m west-south-west, and the George Roper, Black Boy, Holyhead and Gange were all lost on the Lonsdale reefs, their scattered iron visible to divers who know where to look; the wrecks themselves are documented separately. Everything about the dive turns on conditions. It needs Heads slack water, a small swell and no southerly, and The Scuba Doctor is blunt that it is for experienced divers only. When it comes together it is a spectacular free dive; when it does not, the platform is a dangerous place to be.

Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
