Golf Course Reef takes its name from the Mollymook golf course on the headland above Colliers Beach, between Ulladulla and Mollymook Beach. The Marine Life Network gives a depth of 25 m and describes a sparse, kelp-covered reef with colourful sea squirts, hydroids and sponges. That makes it a quieter, less dramatic reef than Burrill Rocks or the Warden Head walls, but it is close to the harbour and seldom dived.

The reef is low rock with a scattering of kelp, patches of sand and some boulders. The invertebrate life is what divers come for: sea squirts in a range of colours, hydroid colonies, bryozoans and sponges, which in turn support nudibranchs and small crustaceans. Fish are the usual Ulladulla mix of red morwong, blue groper, leatherjackets, silver sweep and yellowtail, with eastern blue devilfish and wobbegongs under ledges. Rays and Port Jackson sharks are often seen on the sand in winter.

The depth makes it best for Advanced divers. It suits photographers who enjoy searching for small subjects and divers who want a change from the regular charter sites. Detailed published information is thin, so use this as a starting point and confirm the position locally. The MLN list also mentions a shallow shore dive at a Mollymook beach with patchy reef, boulders and a lost Admiralty-pattern anchor, which may be nearby. Divers who know the reef well should be able to add a proper description; until then, treat the depth and position here as approximate and plan a conservative dive from the anchor line.

Boat access only. Charters and private boats launch from the public ramp inside Ulladulla Harbour, reached off the Princes Highway in the centre of Ulladulla (about three hours' drive south of Sydney); there is trailer parking around the harbour and the dive shop is a short walk away. The reef lies off Colliers Beach at the southern end of Mollymook, below the Mollymook golf course, only a few minutes north of the harbour mouth.

Anchor on the reef in 20–25 m. It is too far out and too deep for a practical shore entry from Colliers Beach.

Mollymook faces east and the reef takes easterly and north-easterly swell; it gets some shelter from southerly swell behind Warden Head. Best in westerly or light southerly weather with swell under about 1.5 m. Heavy rain reduces visibility, and a big swell stirs up the sand around the reef.

Descend onto the reef, follow its edge along the sand at 22–25 m for about 15 minutes, then turn and return over the top through the kelp at 18–20 m, looking closely at the rock for sea squirts, hydroids and sponges, and ascend on the anchor line.

Listed by the Marine Life Network; no current operator publishes it, but Dive Adventures Ulladulla can run it on request. Mainly private boats from Ulladulla Harbour.
