Meet the site
Boat Harbour Point is one of the most popular shore sites on the north-west coast. The Marine Life Network guide rates it 5.5 out of 10 and describes Crystal Bay as sheltered and ideal for beginners on the main beach side. The eastern side runs from a 2 m cove to a cormorant roost in 8-10 m, with wrasse, juvenile zebrafish, sponges, nudibranchs, cup corals and zoanthids, and gorgonian fans, lace bryozoa and tunicates on the northern extension. The western side has 1-3 m boulders around Cascade Rock sloping to 12 m sand. Several leatherjacket species, banded morwong, zebrafish, long-snouted boarfish, bearded rock cod, bullseyes, herring cale and weedfish are recorded, and it is a good night dive.
The Leven Scuba Club lists three main dives here, including routes to Bird Island and finger reefs, with boarfish, trevally, zebrafish, squid, sea pens, rays and prowfish, and warns that good navigation is essential. Local divers typically combine two or three Rocky Cape and Sisters Island sites in a day, choosing the side of the cape that suits the wind and the state of the tide.
The Rocky Cape and Sisters Island area is, in the Leven Scuba Club's words, the best collection of dive sites on the north-west coast. The quartzite of Rocky Cape - some of the oldest rock in Tasmania - forms gutters, ledges, caves and bommies, and the tidal flow along Bass Strait keeps sponges, gorgonians, sea pens and bryozoans well fed. Michael McFadyen, diving here in February 2008, recorded 18-19 °C water and 20-25 m visibility, figures that surprise divers used to the east coast.
Rocky Cape National Park also protects Aboriginal cave sites and coastal heath above the water, and a Parks Pass is required for vehicles. The nearest hyperbaric chamber is the Royal Hobart Hospital, about four hours' drive away, so conservative profiles and oxygen on the boat are essential.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Boat Harbour Point is recorded as Shore/Rock Platform in Tasmania North & North-West. The listed access is shore. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
