Right Point is the southern headland of Cat Bay on Phillip Island's western shore, a kilometre south-west of Flynns Reef and a couple of kilometres short of The Nobbies. Scuba Doctor lists it as a 2–8 m shore reef dive with exploration around the offshore reefs off the point and old jetty pylons in Cat Bay further north, and records the story behind the name: George Bass named Cat Bay in January 1798 because he lost his cat here. The diving is shallow and relaxed.

Off the point a series of basalt reef patches sits on a sand and seagrass floor, each with a kelp cap, undercut edges and gutters between, and the usual Western Port entrance community lives on them – encrusting sponge and ascidians under the ledges, abalone and crabs in the cracks, wrasse, leatherjackets, cowfish, old wives and zebrafish over the top, Port Jackson sharks resting in the gutters in the cooler months, and stingarees and fiddler rays on the sand. The old jetty pylons in Cat Bay are the point of difference: the remains of an early landing, now reduced to stumps and scattered timber, they have become small artificial reefs with sponge and ascidian growth and their own populations of small fish and invertebrates, and they make a worthwhile target for a second dive or a long snorkel. The bay is also one of Phillip Island's better-known surf breaks when a westerly swell wraps in, which is when the site is unworkable; on easterly winds it is calm and clear.

The wooden steps from the Right Point car park make the entry easy and the alternative of entering on one side of the point and exiting on the other adds variety. Right Point suits beginners, snorkellers and divers staying at Cowes who want a quick, easy reef on a day when the south coast is blown out, and it pairs naturally with Flynns Reef and Cowrie Beach along the same road.

From Cowes follow Ventnor Road west for about 12 km past the Penguin Parade turn-off; the Right Point car park is on the northern side of the road just past the Penguin Parade area and before The Nobbies. Wooden steps lead down to the beach on the northern side of the point – a carry of about 100 m. Enter off the sand and swim out to the reefs off the point, or walk round to the southern beach if the northern side is choppy.

The old Cat Bay jetty pylons are further north along the bay and can be reached by a longer swim or a separate entry.

West-facing; best with calm seas and offshore south-easterly winds at high tide. Cat Bay is a surf beach in westerly swell, when refracted waves peel along the point, so wait for a swell under 1 m and an easterly quarter wind. Tidal streams in the Western Port entrance are strong just offshore but mild on the reef; visibility is best on the flood in settled weather and drops after westerly blows.

Diveable year-round; calm winter easterlies often give the clearest water.

Enter from the northern beach below the steps, swim out to the reef off Right Point at 3–5 m and circle the offshore reef patches, keeping the point on one shoulder, to a maximum of about 8 m. Turn at half gas and return to the same beach, or, if conditions favour it, continue round the point and exit on the southern beach with a short walk back to the car. A separate dive can be made on the old jetty pylons in the bay to the north.

No dive shop or dedicated dive charter is based on Phillip Island. Sites are dived by Melbourne clubs (VSAG, Melbourne University Underwater Club, Frankston/Peninsula clubs) and private boats launched at Newhaven or Rhyll; Mornington Peninsula shops (Dive Victoria Group, Portsea; The Scuba Doctor, Rye) run occasional Phillip Island days. Ocean Adventures Phillip Island (Cowes) runs seal-snorkel tours only.
