⚓

A WWII-era New Zealand Navy minesweeper wreck that was sunk by Japanese aircraft on 7 April 1943 while refuelling in Tulagi Harbour, resulting in the loss of five crew. The harbour environment can have challenging visibility due to nearby estuaries and mudflats. The wreck hosts schools of juvenile trevally along with mangrove jacks and batfish, and lionfish are common throughout the structure.

Raiders / F4F Wildcat (Wreck)

Not Set

This site features a US F4F Wildcat aircraft wreck resting at 42 m. Discovered in 2015, the plane is largely intact aside from a missing propeller, with the cockpit area, instruments, and gun sights still in place. Conditions can be silty, and timing the dive for slack or an incoming tide is preferred. Fish life commonly seen around the wreck includes snapper, trevally, and sweetlips.

📍 2.9 km

PBY Catalina Seaplane (Wreck)

Not Set

An upright PBY Catalina seaplane wreck rests on the side of a reef, with the cockpit around 26 m and the tail around 33 m. The airframe is largely intact, though the engines have detached and sit on the seafloor beside the wreck; munitions and machine guns are still present. The wreck is covered in soft corals with some hard coral growth, and attracts schooling reef fish and smaller critters around the structure.

📍 3.0 km

Balydon Shoals

Not Set

Balydon Shoals is a long, shallow reef about 400 m in length with a top around 18 m. The reef top is described as fairly flat and relatively barren, influenced by strong currents running across it. On the southwest side, a striking wall drops off and serves as a focal point where fish gather in the water column, making the site well-suited to drifting dives.

📍 3.1 km

USS Kanawa (Wreck)

Not Set

A 476-foot fleet oiler and freighter that sank on 7 April 1943 after an attack by Japanese aircraft. The wreck lies upright on a sandy seabed, with the bow around 40 m and the stern descending to about 55 m. It attracts large schools of fish around the structure.

📍 4.6 km

Twin Tunnels Reef

⚓

A pinnacle reef that rises from deeper water to around 15 m below the surface. Two vertical shafts drop from the reef top to a chamber, with a cave exit around 36 m.
