Explore Tasmania
Tasmania is the largest island in Australia, found off the South East coastline. It is the coldest part of Australian territories and the diving is temperate. Though the water may be cold, there are some truly beautiful dive sites here that will enrapture any lover of the ocean. There are over 5,000 kilometres of coastline and over 45,000 hectares of marine reserves - there will never be enough time to appreciate all Tasmania has to offer.
The water temperatures are warmest from December to February when they reach 21oC - they can drop below 10oC during the winter months. This is unsurprising, given that Tasmania lies closer to the Antarctic than the tropical reefs of Ningaloo or the Great Barrier Reef. Launceston is the hottest area of the region, with summertime day temperatures averaging 24oC. With 4 distinct seasons, Tasmania is a place of transition - each season offering something different. Though the winters are cold, the visibility is often amazing - often exceeding 40m.
Diving in Tasmania offers some of the most extensive sea caves in the world, with cavernous passageways and sunlight filled antechambers. Another highlight for advanced divers is the deep walls - most dive sites have a maximum depth of at least 40m. The walls stretching down into these depths are covered in yellow zoanthids, creating a yellow cloak which forms a backdrop for the thousands of fish which hang in the blue.
The craggy coastline has claimed more than one shipwreck, the most notable is the Nord which lies between 35 and 42m. Animal lovers will not be disappointed. There are large seal colonies scattered around the coast, which commonly approach divers serendipitously on dives. These inquisitive animals enjoy human interaction and will play with divers. Dolphins and whales can be seen but sightings are based on pure luck.

Diving in Tasmania
Tasmania offers diverse diving, from scenic shore dives to deep wreck explorations. Binalong Bay is a favorite shore dive, featuring coral bommies, kelp forests, and abundant macro life. Maria Island’s Troy D wreck and nearby seal colonies add excitement, while Waterfall Bay’s Cathedral Cave system offers dramatic cavern dives even for beginners.
Advanced divers can explore the SS Nord wreck, lying at 35–42m, one of Tasmania’s best-preserved. Most sites are shore-based, but boat dives to offshore reefs and caves enhance the experience.
The best Months to dive in Tasmania
Diving in Tasmania is possible year-round, with the best conditions from December to April. Water temperatures range from 10°C in winter to around 18°C in summer, so a thick wetsuit or drysuit is recommended.
Visibility is generally excellent, often exceeding 15–20 meters, especially in colder months. However, weather can be unpredictable, and strong winds or swell may affect accessibility to some dive sites, particularly offshore and along exposed coastlines.
