Fisher Point juts into Recherche Bay near Cockle Creek, at the very end of Tasmania's southernmost road. It was the site of a shore-based bay whaling station in the 1830s-1840s, when southern right whales came into the bay to calve and were hunted almost to extinction; ruins and a later pilot station and light remain on the point. The Marine Life Network guide describes a small offshore reef with a nice kelp garden and general reef fish in 4-15 m, reachable by a short walk over Planter Beach or by boat.

It notes that whalebone and implements may still be found on the shallow beaches and that the area has archaeological significance – all such material is protected and must be left where it lies. The kelp garden shelters wrasse, leatherjackets, magpie morwong and juvenile fish, and weedy seadragons may be seen along its edges. The walk from Cockle Creek to Fisher Point is a popular short hike, and the combination of history, coastal scenery and an easy shore dive makes this a rewarding outing for divers camping at Cockle Creek.

Southern right whales have returned to Recherche Bay in recent decades, and in winter and spring divers may be lucky enough to see them in the bay – keep boats and swimmers well away as required by law. The far south has no dive shop or air fills – bring filled cylinders from Hobart or Kingston – and mobile coverage is patchy, so carry a VHF radio and leave a trip plan.

Recherche Bay is at the end of the Huon Highway and the gravel road beyond Southport and Lune River, about 2 hours (110 km) south of Hobart; it is Australia's southernmost road-accessible coastline. The Catamaran River boat ramp at the southern end of the bay is the usual launch; Cockle Creek has camping and is the start of the South Coast Track. The Marine Life Network guide describes a short walk over Planter Beach to Fisher Point (the walking track from Cockle Creek also leads to the point and its lighthouse ruins), or a boat trip from the Catamaran River ramp.

The far south – Port Esperance, Southport and Recherche Bay – opens southward to the Southern Ocean. Southerly and south-westerly swell and strong southerly winds make the exposed sites unworkable and quickly reduce visibility, while northerly and light westerly winds give calm water. Sheltered bays such as Port Esperance and inner Recherche Bay remain diveable in moderate conditions.

Weather changes rapidly and fronts arrive every few days; plan around high-pressure systems in late summer and autumn and watch for south-westerly changes.

Enter from the beach near the point, swim out to the small offshore reef and explore the kelp garden at 6-10 m, then return along the shallows looking at the seabed near the old whaling station without disturbing anything.

No regular operator; private boats and club expeditions. Underwater Adventures Tasmania runs occasional far-south trips (the Acteons are mentioned by Go Dive Tasmania as a kelp-diving area).
