Black Point, on the shore of Fitzgerald Bay north of Point Lowly, is the northern end of the giant cuttlefish breeding grounds. Curious Campers describes the breeding area as spanning Fitzgerald Bay around Point Lowly to Black Point and False Bay, and names Black Point as a quieter option with fewer visitors. The reef here is similar to Stony Point: fragmented limestone slabs and ledges in shallow water, providing crevices where female cuttlefish lay eggs and males display.

In a good season, cuttlefish can be found along much of this shore. Outside winter, the reef hosts leatherjackets, magpie perch, wrasse, blue swimmer crabs and squid, and dolphins frequent Fitzgerald Bay. The trade-off for solitude is access.

There are no facilities, parking is informal and water access is difficult in places, with rough rock at the water's edge. The bay also hosts aquaculture leases. Black Point suits self-sufficient divers and snorkellers who have seen Stony Point and want a quieter experience, or who need a lee from southerly winds.

It is not the place for a first visit or for families wanting easy access. Do not confuse this Black Point with the Black Point shack settlement on the east coast of Yorke Peninsula. As at the other cuttlefish sites, mornings are usually calmest, and incoming tides tend to bring cuttlefish close inshore.

Bring everything you need – water, warm clothes, a thermos – because the nearest services are back in Whyalla, and tell someone your plan, as few people pass along this road in winter. Check the latest sanctuary-zone map before visiting, since boundaries were revised in 2026.

Whyalla is about 390 km (4-4.5 hours) from Adelaide via Port Wakefield, Port Augusta and the Lincoln Highway, or a 45-minute flight. From Whyalla take Port Bonython Road towards Point Lowly and follow the Fitzgerald Bay coast road/tracks north to Black Point (about 35-40 minutes). There are no facilities, parking is informal and water access over rock is difficult in places; scout the entry first.

The road passes aquaculture leases in Fitzgerald Bay.

Upper Spencer Gulf has no ocean swell; wind and tide control conditions. Strong southerly and south-westerly winds blow straight up the gulf and raise a short, steep chop, and northerlies stir the shallow water along the northern shores. Tides are large for South Australia (over 2 m on springs) and run hard around Point Lowly and in the shipping channels, so boat sites should be dived at slack water – visibility is often excellent (15-20 m+) at slack and murky when the tide runs.

Winter (May-August) brings the calmest mornings and cold water (11-13°C); summer water reaches the mid-20s but afternoon sea breezes are common. Black Point faces north-east into Fitzgerald Bay, so it can be sheltered on southerly days when Stony Point is choppy, but northerly winds blow onshore here.

Enter where footing is easiest and follow the reef edge parallel to shore at 2-5 m looking for cuttlefish under ledges, returning the same way.

No operator base; occasionally used by Whyalla Dive Shop and independent divers seeking fewer crowds during cuttlefish season.
