Meet the site
Lighthouse Sponge Gardens is the reef immediately east of the Lighthouse Wall islet below Ulladulla Lighthouse. Where Lighthouse Wall is a drift, this site is normally dived at anchor, and it has a more broken, complex structure. The reef top is at about 10–12 m. From it, a wall drops past 20 m and is cut by gullies, canyons and overhangs, with cracks and crevices running through the reef so that the depth changes quickly from place to place.
As the name suggests, the fixed life is the attraction: sponges of many colours cover the wall and gully sides, along with sea squirts. Wobbegongs and Port Jackson sharks sit in the crevices, eastern blue devilfish hide under the overhangs, and there are schools of yellowtail, one-spot pullers and silver sweep. McFadyen writes that at times the fish are so numerous they obscure the reef. The shallower reef top has kelp and the usual temperate reef fish.
The dive works for Open Water divers who stay on the reef top and upper wall. Advanced divers can explore the deeper gullies. The site is minutes from the harbour and is a good second dive after Burrill Rocks or the North Bommies, or an option when a longer run is not practical. Visibility is usually around 15 m, good for photographing the sponges. Navigation is simple: head out north-east along the wall, turn at half gas and come back over the top. A torch helps in the overhangs, where the sponge colours and hiding devilfish are easy to miss in natural light.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Lighthouse Sponge Gardens is recorded as Reef in Ulladulla. The listed access is boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- 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.
