The Gothenburg is a historic shipwreck located on the seafloor at Old Reef. This site offers penetration diving across a depth range of 9 to 30 metres, with an average depth of 15 metres. Access is by boat only, and the site is suited for advanced divers due to moderate currents reaching up to 1 knot. Visibility typically ranges from 10 to 20 metres. Divers should exercise caution regarding the wreck as a historic site and final resting place. A torch is essential for overhead environments, and a surface marker buoy is required due to pelagic activity in the water column. Plan entries around slack tide to manage currents.

Old Reef is a boat-accessible site located 35 kilometres from the shore, featuring a combination of reef topography and the wreck of the SS Gothenburg. Divers and snorkellers can explore depths ranging from 2 to 20 metres. The site is suited for intermediate skill levels due to moderate currents that can reach 1 knot. Visibility varies between 5 and 20 metres, and the site should only be visited in good sea conditions. Hazards include boat traffic, potential entanglement on the wreck, stinging jellyfish, and currents. Divers should carry an SMB and check local conditions before entry. The habitat supports a variety of reef fish and invertebrates.

Shrimp Reef is a wall and reef site located in Queensland, Australia. The topography features a wall dropping from 20 to 65 metres, though the upper sections at approximately 7 metres are most suitable for beginners. Divers experience mild currents and visibility ranging from 15 to 30 metres. The site supports a variety of reef fish and invertebrates typical of the region. Boat access is required to reach the reef. Divers should monitor their depth gauge closely to avoid drifting deeper than intended along the wall face. The Australian Institute of Marine Science monitors this location for Crown-of-Thorns Starfish outbreaks.
