The Gothenburg is a historical wreck sitting on the seafloor off Queensland, offering penetration diving across a depth range of 9 to 30 metres. Moderate current runs across the structure regularly, so solid buoyancy control and situational awareness matter here. Visibility typically holds between 10 to 20 metres, which rewards divers who take their time working through the wreck's overhead sections. Giant groupers and barracuda hold position around the structure, while reef sharks, eagle rays, and pelagic fish patrol the blue water column beyond the hull. Sea snakes and turtles also turn up with regularity. Best months run June through October when conditions stabilise.

Old Reef combines a reef structure with wreck diving across depths of 2 to 20 metres, giving intermediate divers plenty to explore across a single site. Visibility is variable, so conditions can shift noticeably between visits. A moderate current runs through the site and can strengthen, so staying aware of your position is worth the effort. The marine life here is genuinely varied: turtles, reef sharks, Maori wrasse, potato cod, giant clams, and clownfish are all present, with manta rays and whales also recorded. Boat traffic is a real hazard on ascent, so deploy your SMB early and make a controlled, visible return to the surface.

Shrimp Reef combines a wall and reef structure in Queensland waters, with visibility typically ranging from 15 to 30 metres, making it easy to take in the surroundings. The site runs deep, from 20 metres down to 65 metres, so as a beginner you want to stay well within the shallower section of the reef where you are comfortable and where most of the life concentrates anyway. Currents here are mild, which helps if you are still building your buoyancy skills. Various reef species move through the area, and the clear water means you get a good view of the wall face. Access is by boat, and the best conditions fall between May and October.
