Governor's Island Marine Reserve delivers a genuinely varied dive across reef, wall, pinnacle, canyon, and kelp forest terrain, dropping to 38 metres with visibility regularly pushing 35 metres. Strong currents run through here and demand respect, but they also drive the productivity that makes this reserve worth the effort. Sea whips and sea fans colonise the structure, while butterfly perch, bullseyes, and cardinal fish work the water column. Keep an eye on the substrate for draughtboard sharks and octopus, and scan the rocky edges for longsnout boarfish, old wife, and shaw's cowfish. Cold water and surge add to the challenge, so solid buoyancy control is essential.

Diamond Island's kelp forests offer a genuinely dramatic introduction to Tasmanian diving. Towering kelp creates a green, cathedral-like environment that filters the light and shelters various reef species living among the structure below. Visibility can reach an impressive 40 metres, though 10 to 20 metres is more typical. The site runs from shallow snorkelling depth down to 40 metres, well into deep diving territory, so beginners should stay in the shallower sections. Be aware that currents here can run strong, the water is cold year-round, and the kelp itself presents a real entanglement risk, so always dive with a buddy and move calmly through the forest.

Bicheno Bay offers a wide depth range, from shallow reef at 4 metres down to 38 metres of deep diving territory, with visibility regularly stretching to 30 metres in the cold, clear Tasmanian water. Moderate currents run through the bay and can strengthen, so keep an eye on conditions and plan your dive accordingly. The marine life here is genuinely varied: weedy seadragons reward patient, slow divers, while butterfly perch, boarfish, morwong, trumpeter, cowfish, and crayfish populate the reef. Fur seals and dolphins make occasional appearances, and whales pass through seasonally. Surge and boat traffic are real considerations, particularly on shallower sections.

Waub's Bay is a gentle shore dive that introduces beginners to the cold-water reef systems Tasmania does so well. Depths run from 4 to 15 metres, giving new divers room to take their time, and visibility can stretch to 30 metres on a good day, though 5 to 10 metres is more typical. The reef sits beneath a kelp forest, so expect filtered light and dense structure. Take it slow and you'll find weedy sea dragons, seahorses, cuttlefish, and cowfish tucked among the sponges. Eagle rays and bullrays pass through, and scorpionfish sit motionless on the bottom, so watch where you put your hands. Current is generally mild, but surge can catch beginners off guard close to shore.

Apsley Waterhole is a freshwater snorkelling site in Tasmania where the main draw is spotting Australian Grayling, a native migratory fish found in select Tasmanian waterways. The water is shallow and calm, making it accessible for beginners and non-swimmers comfortable with snorkelling gear. Visibility varies depending on recent rainfall and season, so conditions are not guaranteed. The water is cold year-round, so a wetsuit is strongly recommended even in summer. The best time to visit is during the summer months of December through February. Basic facilities including parking and toilets are available on site.

Friendly Beaches offers shore diving along a Tasmanian reef where sponge gardens form the visual backbone of the site. The waters are shallow and calm, though moderate currents run through, so plan your entry and exit accordingly. Visibility is variable, which is worth checking before you commit to the dive. Australian fur seals and dolphins move through the area, while butterfly perch are a reliable reef presence among the sponges. Cold water is a constant here, so a drysuit or a well-rated wetsuit is the sensible choice. Best conditions run from December through May. Watch for surf and rip currents at the shore entry.

Picnic Island is a gentle, accessible snorkel site in Tasmania suited to beginners, with shallow, calm waters that make it easy to explore at your own pace. The site sits within boat range and is best accessed through a local charter. Currents can vary, so check conditions before heading out, and visibility shifts depending on the day. Cold water is a constant here, so a wetsuit is essential. The underwater life is the real draw, with Australian fur seals and bottlenose dolphins appearing regularly, while abalone, crayfish, and sea urchins inhabit the reef below. Migrating whales pass through seasonally.

Wineglass Bay offers shore-based snorkelling in shallow, calm waters, making it a welcoming choice for beginners. The reef environment is home to weedy seadragons, those wonderfully camouflaged relatives of the seahorse, so take your time and look carefully rather than covering distance. Seals and dolphins also move through the area, and during the right season, whales are sometimes spotted from shore. Visibility varies, so conditions can change between visits. The water is cold year-round, so a wetsuit is essential regardless of the air temperature. The best window runs from December through to May.
