Rose Bay lies just south of Murray Bay on Bowen's northern headland, beside a small residential community, and it is the most convenient of the Bowen bays for a relaxed shore dive: park, gear up on the grass and walk into the water. The North Queensland Underwater Explorers Club describes the northern end of the bay, around the rocky point, as the dive, with depths of about 5–7 m. Staghorn coral dominates here, forming thickets with occasional patches of lettuce coral.

The staghorn supports its own community of small fish, and the club notes nudibranchs in large numbers and honeycomb moray eels among the rocks. It is a site for slow exploration and macro rather than big animals. Navigation is the local joke.

The staghorn fields look much the same in every direction, and in low visibility divers become disoriented easily; the club calls this section 'Bowen's Bermuda Triangle'. A compass heading taken at entry and a plan to return along the shoreline solve the problem. Fishing tackle and anchors litter parts of the bay, so buoyancy control and a cutting tool are worthwhile.

Visibility is typically 2–8 m. The club suggests slack water at the top of the tide, which gives more depth over the reef and easier exploration of the point. The club also notes that Cyclone Debbie in 2017 may have damaged the delicate staghorn structures since its description was written, so current coral condition may differ.

For Bowen locals and visitors with their own gear, Rose Bay is an easy, uncrowded snorkel and shallow dive.

Bowen is on the Bruce Highway about 2.5 hours' drive south-east of Townsville and about 1 hour north of Airlie Beach/Proserpine. The town's northern beaches – Queens Beach, Horseshoe Bay, Murray Bay, Rose Bay and Grays Bay – lie on the headland north-east of the town centre, reached via the Lower Don Road/Soldiers Road and signposted beach turn-offs near the Bowen aerodrome. Follow Rose Bay Road until it becomes Bluewater Parade; there is a small car park with a grassy area for gearing up.

Walk a few metres to the beach and enter from the sand, or swim north-east to the rocky point at the northern end of the bay where the coral is concentrated.

Bowen's bays sit on the northern side of a headland, which shelters them from the prevailing south-east trades, but strong south-westerlies and northerlies make them choppy. Visibility is typically 2–8 m – down to 2 m after high wind, 7–8 m in ideal calm conditions – and it deteriorates after coral spawning (late November–December) and wet-season rain when the Don River discolours the water. Dive in the morning before the sea breeze, on a calm day at high-tide slack.

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). Cyclone Debbie (2017) crossed near Bowen and damaged delicate coral in the bays.

NQUEC recommends slack water at the top of the tide for the best conditions and to explore the point.

Enter from the beach, head to the rocky point at the north end and explore the staghorn thickets at 5–7 m. Use a compass for the return – NQUEC jokes that this section can be 'Bowen's Bermuda Triangle'.

No dedicated dive shop in Bowen at time of research – divers dive independently or with NQUEC club trips; nearest dive centres and air fills are in Airlie Beach (e.g. Whitsunday Dive Adventures).
