Bunga Head is a headland in the southern part of Mimosa Rocks National Park, a few kilometres north of Tathra.

Reefs off the Mimosa Rocks headlands are rocky, with kelp and crayweed in the shallows and boulders and ledges in deeper water. Nearby documented sites give a sense of what to expect: at Tathra Wharf, the reef is covered in sponges, sea squirts, soft corals and thousands of gorgonians, with schools of yellowtail, leatherjackets, blue groper, blackfish and wrasse. Similar growth may occur at Bunga Head's deeper reefs, together with red morwong, sweep, wobbegongs and Port Jackson sharks.

The site is only accessible by boat for practical purposes and suits divers with their own vessel on a calm day. It is little visited, so it may reward exploration, but there is no information about the reef's layout or depth, and no operator support. The coastline here is dramatic, with volcanic rock formations like those at Mimosa Rocks further north, so the boat trip itself is scenic. Allow plenty of time for the return run to Tathra, as afternoon sea breezes can build quickly.

Boat access from the Kianinny ramp at Tathra, running north about 5 km (10–15 minutes) past Tathra Head to the headland; or from Bermagui harbour further north. By road the headland is inside Mimosa Rocks National Park off the Tathra–Bermagui Road, with walking access only. No operator runs trips here.

Carry full safety gear, as there is no nearby help.

The headland is exposed to swell from north-east through south. It needs calm seas with swell under about 1.5 m and light winds, ideally westerly. Visibility falls after heavy rain when the Bega River and nearby lagoons flush.

Afternoon north-easterly sea breezes in summer make the return run rough, so dive in the morning.

Treat as an exploratory dive: anchor on the reef off the headland, follow the reef on a compass heading and return to the anchor. Set a conservative turn pressure and carry an SMB in case you surface away from the boat.
