Lake McKenzie is a perched lake on K'gari, characterised by its white silica sand basin and soft freshwater. The site offers shallow depths ranging from 0 to 7 metres, with an average of 5 metres, making it a suitable environment for beginners. Entry is directly from the shore. Due to the lake's slightly acidic chemistry, the water supports minimal aquatic life. Divers and snorkellers should be aware that dingoes frequent the area; visitors are prohibited from taking food or drink, other than water, to the lake shore and must use designated fenced picnic areas near the car park.

The SS Maheno wreck is a historic vessel resting in the surf zone off K'gari, Australia. The site is shallow, with the wreck structure located between 0 and 1 metre of depth. Due to its position in the surf, the area is subject to strong rip currents and dangerous surf conditions. The wreck itself consists of decaying, sharp, and unstable metal components. Access to the wreck is prohibited for safety reasons. Visibility in the area typically ranges from 5 to 10 metres. While the site is often associated with beginner-level activities, the presence of strong currents and hazardous debris makes it unsuitable for swimming, snorkelling, or diving.

The Ex-HMAS Tobruk is a decommissioned Australian Navy vessel resting as an artificial reef off the Bundaberg Coast. This wreck dive spans depths of 11 to 30 metres, with an average depth of 20 metres. Access is by boat only, and the site is suited for advanced divers due to strong currents and the potential for drift diving conditions. Visibility ranges from 8 to 25 metres. Divers should maintain contact with the structure and their guide at all times. The site is available for both day and night diving, with guided tours and equipment rental available locally.
