Bremner Point is the rocky headland between Alma Bay and Geoffrey Bay, and the North Queensland Underwater Explorers Club rates its fish life higher than that on the Moltke wreck nearby. It is a shore dive from the old vehicle-ferry landing at the end of Armand Way, entering down the disused ramp or from a flat rock that marks an old jetty footing. Along the headland a shallow wall runs at 7–8 m, with detached coral heads standing off it, small caves and overhangs cut into the granite, fan corals and red and white sea-whip corals.

A torch is useful for peering into the caves and under ledges. The fish list is long for a shore dive: juvenile red emperor, bicolour angelfish, batfish, beaked butterflyfish, grassy sweetlips, bannerfish, Moses perch, schools of yellowtail fusiliers and diamond-scale mullet. The point also holds the scant remains of the Lallah Rokh, a timber ketch carrying timber that was lost here, presumed run aground, in 1896; remains lie at 5–7 m and can be reached by boat or a subsurface swim from Alma Bay, though little is recognisable.

The NQUEC approach is a simple out-and-back along the headland, turning at a set pressure such as 120 bar, and it suggests the 'follow-along' method where a surface watcher tracks the diver's bubbles. The wall is shallow enough for new divers, but the point is exposed to south-easterly chop and tidal flow, so it suits divers with a few shore dives behind them. Like the rest of Arcadia's bays, Bremner Point lies in a green zone.

Combined with the Moltke and the Geoffrey Bay trail, it makes a good day of shore diving without moving the car.

Magnetic Island is reached by SeaLink passenger ferry from the Breakwater terminal in Townsville to Nelly Bay (about 20 minutes, frequent daily services) or by the vehicle ferry from Ross Street, South Townsville (about 40 minutes). Buses, hire cars and 'topless' mokes run from the Nelly Bay terminal to Arcadia, Horseshoe Bay and Picnic Bay. Drive or bus to Arcadia and park at the end of Armand Way beside the old vehicle-ferry landing on Geoffrey Bay.

Enter either down the disused ferry ramp or from a flat rock near the old track (a historic jetty footing), then swim east along the rocks towards the point. Gear carry is under 50 m. The point can also be reached by a long subsurface swim from Alma Bay or by boat.

Magnetic Island's bays are sheltered from different winds depending on which side they face. The dominant south-east trade winds (15–25 knots, April–September) chop up exposed eastern and southern bays and stir up silt, so the island's best diving comes in the calmer months of August–December and on mornings before the sea breeze. Visibility is usually 3–8 m and occasionally 10–15 m; it drops sharply after strong winds, big spring tides and wet-season rain (January–April) when Ross River and Burdekin run-off discolour the water.

Dive at slack water, ideally high tide. Sargassum seaweed blooms in the hotter months can smother shallow reef flats. Marine stinger season (box jellyfish and Irukandji) runs roughly November to May – wear a full-length stinger suit or wetsuit with hood and gloves, carry vinegar.

Stinger nets are installed at Alma Bay, Picnic Bay and Horseshoe Bay in season. The point takes the brunt of south-easterlies; choose a calm day at high-tide slack.

Enter at the ferry ramp, follow the shallow wall east along the headland at 5–8 m with the rocks on your left, checking small caves with a torch, and turn at 120 bar (NQUEC's suggestion). Return shallower along the same route. A surface watcher can follow bubbles.
