Meet the site
The Sponge Garden Drift is the gentle introduction to the Heads drift dives that Queenscliff operators run inside Port Phillip when the ebb is running: a live-drop drift over the sponge beds south of the pier that lets divers experience the tidal current without the depth and exposure of the Rip itself. The Scuba Doctor describes it as taking you over massive sponge gardens and shallow reefs inside Port Phillip, and says it is the colours of the sponges that make the dive stunning, which is exactly right. The tidal flow through the Heads delivers plankton on every tide and the seabed here is carpeted with filter feeders in a density found nowhere else in the bay: finger, cup, fan and encrusting sponges in orange, yellow, red and purple, sea tulips, ascidians, bryozoans, gorgonian fans and soft corals on the harder ground. The dive passes through three zones as the stream carries you south: low shallow reef at 12 m, then the open sponge gardens at 14-16 m, then larger reef formations and bommies to 20 m near Torpedo Reef. Fish are variable, as they are on all drifts, but old wives, magpie perch, boarfish, leatherjackets, blue-throat wrasse, sweep and the occasional blue devil, seadragon or seal are all seen, and old bottles and other relics of Queenscliff's shipping history litter the sand between the sponges. Because it is inside the Heads it is sheltered from swell and is the operators' fallback when the outside sites are too rough. It suits advanced or experienced open-water divers who are comfortable with drift procedures and a surface marker, and it is often the second dive of a Heads day after a wall or wreck. Jane Headley's video Sponge Hollows shows it well.

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.
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.
