Pelorus Island is the northernmost of the Palm group's larger islands, a 2.9 by 1.7 km national park island managed by Hinchinbrook Shire Council where self-sufficient bush camping is allowed without booking. Its north-western beach is the base for the North Queensland Underwater Explorers Club's Pelorus trips, and the Front Reef directly off that beach is the easiest dive on the island. The club describes a gentle reef slope and shallow wall at 6–10 m with sand patches and colonies of staghorn coral, entered about 250 m above the southern end of the beach – near the creek, where gear donning is easiest.

Small reef sharks patrol the slope, juvenile manta rays come in on the high tide, and in winter humpback whales pass close enough to be heard underwater. Typical fringing-reef fish – damsels, parrotfish, wrasse, butterflyfish, rabbitfish and small groupers – are abundant, and the shallow wall hides nudibranchs and crustaceans. Front Reef is an excellent night dive.

The slope is simple to navigate, the entry is directly off camp, and the club uses a campfire on the beach as a navigation aid for returning divers. At night the staghorn thickets are full of sleeping fish, shrimps and crabs. The reef is zoned Habitat Protection, so it can be fished, and divers may meet some lost tackle.

Tidal current is mild here compared with the Northern Point further along the beach, and the beach faces away from the prevailing trades, giving a sheltered option in most weather. For campers and boaties willing to make the trip, Pelorus Front Reef offers genuinely independent shore diving on an uninhabited Great Barrier Reef island – rare in Queensland – with the bonus of winter whales and occasional mantas.

Boat only. The Palm Island group lies 20–25 km off the coast between Townsville and Ingham. The quickest access is from the Lucinda or Dungeness boat ramps near Ingham (about 1 hour 20 minutes' drive north of Townsville via the Bruce Highway), from which a small boat reaches Orpheus and Pelorus in about 30–45 minutes across Halifax Bay; Taylors Beach ramp is an alternative.

From Townsville the run is roughly 1.5–2 hours. Orpheus Island Lodge guests arrive by helicopter or seaplane and dive from the lodge's boats. Campers on Orpheus (QPWS permit) and Pelorus (self-sufficient, Hinchinbrook Shire Council) usually arrive by private boat or water taxi.

Use public moorings where available and check no-anchoring areas. On Pelorus, land on the north-western beach; the creek mouth gives the easiest spot to kit up and enter.

The Palms are high continental islands, so some shore always offers a lee, but the Orpheus–Pelorus channel and exposed points are hit by the south-east trades (15–25 knots, April–September) and by strong tidal streams – springs can produce currents that make the points undiveable except at slack water. Visibility is typically 6–10 m and reaches 15 m in the winter channel; it falls after strong winds and during the wet season (January–April) when the Herbert River floods discolour the water. The calmest, clearest conditions come in the October–December build-up.

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. Cyclone season November–April; tropical lows and cyclones can close sites and damage coral (TC Yasi 2011, TC Debbie 2017). The north-western beach is sheltered from the south-east trades.

Enter by the creek, swim out to the reef slope and follow it with the reef on one shoulder at 6–10 m, then return in the shallows. At night, NQUEC uses a campfire on the beach as a navigation aid.

Orpheus Island Lodge – private dive charters for guests to local reefs (minutes away) and the outer reef (~75 min), plus Discover Scuba shore dives; otherwise private boats from Lucinda/Taylors Beach, campers and NQUEC club trips. No scheduled public dive trips.
