Meet the site

The Leven Scuba Club describes 5 Mile Reef as one of the few local dives where 30 m visibility can be experienced: a large offshore bommie brimming with pelagics, in 25-50 m. It stresses that it is for experienced divers only and only from a live boat. No further description or position has been published; the name implies a distance of about five nautical miles from its reference point on the coast. It is a site for technical divers. 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.

Some details in this record need confirmation. Check the source information and speak with a local operator.
