Meet the site
Tryon Island is a small cay of about 11 hectares in the Capricorn Group, close to North West Island. Like its neighbours it is a national park with Pisonia forest and Cordia trees and is an important nesting site for seabirds and turtles. Camping is sometimes permitted for groups of up to about 30 people, though the island has been closed at times for habitat recovery. The Marine Life Network describes the reef as a good snorkel spot but notes that boat access is tricky: the island is surrounded by reef flat that dries at low tide, and landing or tender access must be timed for high water. Divers can expect shallow coral gardens, turtles, reef fish and reef sharks along the reef edge. Tryon has appeared on liveaboard itineraries touring the Capricorn Group, where it would usually be visited as a shallow dive or snorkel stop. There is no operator based here, and visitors must be self-sufficient. The island suits snorkellers and relaxed divers with access to a private boat or liveaboard, and anyone wanting to experience a small, undeveloped cay. As with all the Capricornia Cays, nesting birds and turtles take priority: check QPWS for closures and camping availability before planning a visit. Detailed dive information for specific sites around Tryon is not published, so conditions and depths given here are estimates based on similar cays.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Tryon Island Reef is recorded as Island in Heron Island & Capricorn Group. The listed access is boat (multi-day/liveaboard). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
