Whisky Bay is a small, west-facing beach between Picnic Bay and the Darby River on the Prom's northern beaches road, and it is the best-documented shore dive at Wilsons Promontory, with a species list on Scuba Doctor that runs from wrasse to whiting. The feature is, in the listing's words, a great big long rock wall running for about 300 to 500 metres out from shore – a granite reef along the southern side of the 200 m beach that gives the dive a spine to follow out and back in 1–12 m. The wall is kelp-forested on top, undercut into ledges along its base, and edged by sand and seagrass, and it carries a remarkable range of life for such a shallow site: wrasse, trevally, mullet, snapper, whiting, blackfish (luderick) and zebrafish over the reef and sand, stingrays and Port Jackson sharks under the ledges and on the sand, abalone and crayfish in the crevices (protected – Whisky Bay is inside the marine national park), nudibranchs on the sponges, and sea dragons in the kelp.

Minimal current and no need for slack water make it the most relaxed dive on the Prom's western coast, and Scuba Doctor points out that it is suitable for both snorkelling and scuba, so a diver can carry on snorkelling the inner wall after the cylinder is empty. The 400 m walk from the car park along Whisky Creek and over the dunes is easy by Prom standards. The bay's only limitation is its exposure to the west: it needs a light easterly and a small swell, and on the frequent south-westerly days it is a surf beach.

Whisky Bay suits beginners, families and anyone wanting a long, unhurried shallow dive with seadragons and sharks in clear water; it is arguably the best shore dive on the Prom for the effort involved.

Turn off Wilsons Promontory Road (C444) into Whisky Bay Carpark Road about 5 km before Tidal River and park at the end. Follow the track for some 400 m along Whisky Creek and over the sand dunes to the 200 m beach – 10 minutes each way with gear on a good track. Enter off the sand and swim out along the rock wall on the southern side of the bay, which runs 300–500 m out from shore.

Exit onto the same beach. Picnic Bay is 700 m south with its own car park and toilets.

West-facing into Bass Strait; best with a light offshore easterly wind, calm seas and minimal swell, at any tide (Whisky Bay tide predictions). Any south-westerly or westerly swell produces surf on the beach and surge along the wall. Minimal current, per Scuba Doctor.

Summer and autumn easterly-wind days; the beach is popular with swimmers in summer.

Enter off the beach and follow the rock wall seaward on its northern side at 4–10 m, looking under the ledges for crayfish and Port Jackson sharks and along the kelp edge for seadragons, out to 12 m. Cross over the wall and return on its southern side to the beach; when air runs low, finish with a snorkel along the inner wall, as the listing suggests.

No operator. Shore dives and snorkels done by campers at Tidal River and by clubs (Dive La Trobe, VSAG, Melbourne University Underwater Club) on Prom camping trips; No air fills at Tidal River or Port Welshpool; the nearest compressor is roughly 100 km away (Melbourne's south-east or Inverloch/Leongatha area by arrangement) – bring all cylinders or a portable compressor
