Meet the site
Tinderbox is Hobart's home shore dive and, as the Parks and Wildlife Service puts it, Tasmania's most accessible marine reserve. It was one of the state's first four marine reserves, declared in September 1991 alongside Ninepin Point, Governor Island and Maria Island, and was later expanded. It is a fully protected no-take area: fishing and other extractive activities are prohibited, and the difference shows. The older Marine Life Network guide notes that before protection, stocks of fish, crayfish and abalone were exceedingly low. The reserve's reefs are narrow bands of rock running along the shore. To the east of the boat ramp they drop to 6-10 m, while to the south-west they reach about 5 m before giving way to sand. The Parks leaflet lists habitats of kelp forest, sponge gardens, seagrass beds and soft sediments, with 77 species of macroalgae and 60 fish species recorded. Highlights include big-belly seahorses, rock lobsters, bastard trumpeter, senator wrasse and octocorals, and weedy seadragons are regularly seen. On the sand and silt beyond the reef divers find brittle stars, cardinalfish, octopus, craylets and lace bryozoans. The shallow gulches east of the ramp are ideal for snorkelling, and Tinderbox has long hosted a marked snorkel trail for learners and families. Most Hobart dive shops use Tinderbox for open-water training, and it is a very popular night dive. Visibility is modest by ocean standards and drops sharply after rain, but the sheltered position means it can be dived in almost any westerly weather. Parks asks divers to avoid damaging fragile life, not to hold onto the reef, and to dive in small groups. Close by, 200 m from the ramp and marked by moorings, lies the Tinderbox artificial reef.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Tinderbox Marine Reserve is recorded as Shore/Rock Platform in Hobart & Derwent. The listed access is shore or boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.

- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.

Is Tinderbox Marine Reserve suitable for my certification?

Can I book Tinderbox Marine Reserve through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
