Doctors Rocks offers a mix of reef and pinnacle diving accessible from shore, making it a solid choice for intermediate divers exploring Tasmania's southern waters. Depths run from 3 to 20 metres, and visibility regularly reaches 12 to 40 metres, particularly during the summer months from November through March. Kelp forests are a defining feature here, creating a layered environment where various reef species move through shifting light and structure. Currents are variable, so checking conditions before entry is worth the effort. Watch for boat traffic near the entry point and take care around sharp coral throughout the dive.

Boat Harbour's South Rocks offers a reef dive that rewards intermediate divers willing to read the conditions carefully. Shore entry drops you into a kelp and sponge-covered reef system that extends from the shallows down to 22 metres in the deeper sections. Visibility swings considerably, anywhere from near zero to 25 metres depending on swell and season, with the clearest water typically arriving in the summer months from November through March. Gorgonians and encrusting sponges decorate the rocky structure, while wrasse and leatherjackets are regular company. Seals occasionally investigate divers, and both seapike and dolphins are possible sightings. Moderate to strong currents and rip currents demand attention, so plan your entry and exit around conditions.

Glory Hole is a cave and reef site in Tasmania that suits beginner divers and snorkellers looking to explore an enclosed underwater environment. The cave itself is the main draw, sitting at depths of 10 to 13 metres where mild currents keep conditions manageable. Visibility ranges widely from 10 to 40 metres, so on a good day you can see clearly across the reef surrounding the cave entrance. Various reef species inhabit the area, giving you plenty to observe as you explore. Because the cave creates an overhead environment, even beginners should stay aware of their position and avoid going deeper into it than feels comfortable.

Rocky Cape National Park offers reef diving along a rugged Tasmanian coastline where kelp forests dominate the shallows and the terrain drops to around 22 metres. Visibility varies considerably depending on conditions, so checking the forecast before you commit is worthwhile. Mild currents keep diving manageable for intermediate divers, though cold water requires a quality wetsuit or drysuit. The reef hosts wrasse, leatherjackets, large rays, and seapike moving through the kelp, while sponges and gorgonians appear in deeper sections. Seals are encountered here, and dolphins and whales pass through during the summer and autumn months.

Bass Strait is a serious body of water, and diving here reflects that. Strong currents and cold temperatures are the norm, so solid buoyancy control and dry suit experience will serve you well. Depths run from 6 to 20 metres across a varied terrain of reef, kelp forest, walls, and canyons. Visibility is highly variable, so conditions can shift dramatically between dives. The marine life is the payoff: Australian fur seals are frequently encountered, and the strait sits along migratory corridors used by humpback whales, southern right whales, and blue whales. Weedy sea dragons, octopus, mosaic leatherjacket, and Maori wrasse inhabit the reef structure.
