Flinders Reef
The highest coral diversity in Moreton Bay, on a rocky reef north of Moreton Island.
Flinders Reef, north of Moreton Island, carries the highest coral diversity of any reef in the Moreton Bay region and is a marine national park zone.
It is a rocky reef with substantial coral growth rather than a true coral reef, producing a mix of tropical and subtropical species that shifts through the year.
The reef is exposed and trips are weather-dependent, but visibility is usually the best available near Brisbane.
