Trial Harbour Reef is a shore dive on Tasmania's rugged west coast, best suited to experienced divers comfortable managing variable currents and surf entries. Rip currents and breaking waves demand careful timing and solid water-reading skills before you commit to an entry. Once in, the reef hosts a range of local species typical of cool temperate Tasmanian waters. Visibility varies considerably depending on swell and conditions, so picking a settled day pays off. Summer through autumn, from December to April, offers the most manageable window. Cold water is a constant here, so a well-fitted thick wetsuit or drysuit is non-negotiable.
