Meet the site
The Leven Scuba Club lists several boat dives in the Port Sorell estuary, including an excellent site at Penguin Island with sponge gardens, nudibranchs and seahorses in 8-15 m. It notes that estuary dives are restricted to high tide. The estuary's tidal flow feeds sponges and other filter feeders, and its seagrass and sponge habitats suit seahorses. Details beyond the club's summary are not published, and the estuary is also popular with boaters and anglers, so fly a dive flag. Local knowledge from Leven Scuba Club members is the best way to get the most out of it, and first-time visitors should ideally dive it with someone who knows the site and the tide.
The central north coast between Wynyard and Port Sorell is the home water of the Leven Scuba Club at Ulverstone, whose site list is the main modern source for it, supplemented by the older Marine Life Network guide. The towns of Burnie, Ulverstone and Devonport sit right on the coast, so many sites are within minutes of a ramp or car park, but the reefs are generally low and weedy, visibility is often 5-10 m, and the coast is open to Bass Strait's northerly and westerly weather.
Devonport is the Spirit of Tasmania ferry terminal, which makes these sites the first and last dives for many interstate visitors bringing their own gear. There is no hyperbaric chamber in the north - the nearest is the Royal Hobart Hospital, about 3.5 hours' drive - so dive conservatively, especially on the deeper offshore sites.
