Narrawallee is a quiet beach village just north of Mollymook, with a small inlet that opens to the sea at the northern end of the beach. Expect a snorkelling and easy shore dive rather than a significant scuba site.

The inlet mouth has sand banks, seagrass and weed beds where tidal flow brings in clearer ocean water on the flood. Around the rocks at the ends of the beach there is shallow reef with kelp and crayweed. The fish are those of NSW estuary mouths and shallow reefs: bream, luderick, whiting and flathead on the sand, leatherjackets, sweep and small wrasse around the rocks, and stingrays and fiddler rays in the shallows. Octopus and small cuttlefish are sometimes seen. Weedy sea dragons occur on shallow kelp reefs along this coast, but no records specific to Narrawallee were found.

The site suits snorkellers and new divers who want an easy swim, and it is a family-friendly beach. It is exposed to swell and affected by tides and rain, so conditions need to be right. For a proper ocean dive nearby, the Ulladulla boat sites and the Bannister Head shore dive are better documented options, and the local shop can advise on current conditions.

From Ulladulla drive north through Mollymook on Mitchell Parade or take the Princes Highway north and turn right into Matron Porter Drive to Narrawallee. Park at the Narrawallee Beach reserve or near the inlet off Victor Avenue. It is a short walk across sand to the water.

Enter from the beach in the lee of the headland on small swell days, or snorkel the inlet mouth around the top of the tide.

The beach faces east and takes most swell; only dive or snorkel on days with less than about 1 m of swell. The inlet has tidal flow, strongest on the run-out, and water clarity is best near the top of an incoming tide after dry weather. After heavy rain the inlet runs brown and visibility is very poor.

North-easterly afternoon winds make the beach choppy in summer.

Snorkel or dive the inlet mouth around high slack tide, drifting gently in on the flood over sand and weed. On calm ocean days, enter at the headland end of the beach and follow the rocky reef edge at 4–8 m, turning at half gas.

No operator lists Narrawallee as a scheduled site; divers and snorkellers visit independently. Dive Adventures Ulladulla is the nearest shop for hire and advice.
