Martin's Mecca is a shallow reef site situated off Thursday Island, Australia. This location is suitable for beginners and those new to underwater exploration, offering calm, current-free conditions. Access to the site is by boat only. Visibility is variable and can change significantly between visits, with low visibility identified as the primary hazard. Divers and snorkellers should enter the water slowly from the boat and maintain close contact with a guide or buddy. It is recommended to check local conditions before departure, as arriving earlier in the day may provide better visibility before wind or boat traffic affects the water.

The Quetta is a 19th-century passenger steamship wreck located in the Torres Strait, Australia. Resting at depths between 10 and 43 metres, with an average of 20 metres, this site is strictly for advanced divers. The defining characteristic is the extreme current, which can exceed four knots, necessitating dives only during the short slack tide window. Divers often use a descent line to reach the wreck. Due to the depth and potential for entanglement, careful decompression planning is required. Visibility is typically around 10 metres. Access is by boat only, and divers should coordinate closely with their skipper regarding the specific slack water timing.
