Spray Point is the headland on the Blairgowrie ocean coast where the back-beach limestone has been carved into its most dramatic form: deep undercuts, great overhangs and, on the eastern side of the point, a series of sea caves that give the site its name. The Scuba Doctor lists it at 5–15 m for Advanced divers and calls it a great crayfish and abalone site, and both are true – the overhangs shelter southern rock lobsters in numbers unusual for a shore dive, and blacklip abalone are thick on the shaded rock. Divers can head out to the offshore reef, a field of ledges and bommies in 10–15 m with kelp on top and sponge gardens beneath, or work eastward along the undercut face toward Montforts Beach, where the Caverns open at the base of the cliff.

The caverns are daylight zones rather than true caves, but they are large enough to swim into, roofed with jewel anemones and sea tulips, and home to Port Jackson sharks, draughtboard sharks, bullseyes and the occasional blue devil. Sweep, old wives, boarfish and wrasse patrol the outer reef, and weedy seadragons sit in the kelp. Everything about the site demands respect: it faces directly south-west into Bass Strait, the caverns amplify surge, and the source is blunt that it is affected by rips, currents, swell and strong winds and can be very dangerous.

The requirement is the standard back-beach one – flat seas, swell under about 2 m with a long period, light northerly to north-easterly winds after several days of the same – and it should be dived with someone who knows the entry. Spray Point suits experienced Advanced divers with rock-platform skills who want lobsters, overhangs and cavern diving from shore; it is not a snorkelling or novice site.

From Point Nepean Road at Blairgowrie take Spray Point Road south to the small car park at its end. A track leads down to the point; enter from the rock platform in a sheltered gully at low tide and swim out to the offshore reef or east along the point toward Montforts Beach, where the caverns lie. Exit by the same gully.

Parking is very limited and the climb back is steep.

The back beaches face south-west into Bass Strait and are safe to dive only in rare flat conditions: The Scuba Doctor's rule of thumb is swell under about 1.5–2 m with periods of 10 seconds or more, usually only after three or four days of northerly to north-easterly winds, with light northerly winds on the day. Any southerly or westerly wind, or a fresh swell, makes the entries lethal. Dive around low tide when the limestone platforms are exposed and the gullies are sheltered, and abort if there is white water over the entry.

Rips and tidal streams near The Rip run even on calm days, and conditions change within an hour. Winter high-pressure systems bring the calmest spells; summer sea breezes rule out afternoons.

Enter from a gully on the point at low tide, drop to 6–8 m and follow the undercut face east toward the Caverns, exploring overhangs and cave mouths in 8–12 m without penetrating beyond daylight; continue to 15 m on the outer reef if calm. Turn at half gas, return along the face and exit through the entry gully between sets.

No regular operator. The Scuba Doctor (Rye) and Peninsula clubs run occasional guided shore dives when conditions allow; otherwise experienced private groups only.
