Meet the site

Trigger Happy is one of three Flinders Reefs sites named on Mike Ball's Yongala & Coral Sea expedition itinerary, alongside Fan Fair and Cod Wall.

No description of the site itself was found. The name suggests triggerfish, and the Coral Sea is home to titan triggerfish, which nest on sand and rubble and defend their nests vigorously during the breeding season, and to clown, orange-lined and red-toothed triggerfish that crowd reef walls. Whether the name refers to a nesting area, a particular abundance of triggerfish or something else entirely is not known.

The general character of Flinders gives an idea of what to expect. Mike Ball describes vertical walls dropping more than 300 m, with 40 m-plus visibility, soft corals and massive sea fans, and sharks, tuna and barracuda. Cruising the Edge reports tiger and tawny nurse sharks and yellowfin and dogtooth tuna in the area.

This record is provisional. If titan triggerfish are nesting, divers should be aware that they defend a cone-shaped territory extending upward from the nest, and should swim away horizontally rather than upward if a fish charges. The crew briefing will cover the site's layout and depth. It suits intermediate divers, and the entry should be updated when an operator description becomes available.

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

Research this site before booking

Trigger Happy (Flinders Reef) is recorded as Reef in Coral Sea. 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.
