Outer Rock has the second highest coral cover (80%) of the Keppel Islands.
Protected from floods by its distance from the mouth of the Fitzroy River, the site is an important habitat for corals and a popular fishing spot.
Fringing coral surrounds Outer Rock, so it is difficult to anchor without breaking coral.
Although the number of coral species is much less than at Humpy Island, divers can see amazing fish life, including pelagic (ocean-dwelling) species such as mackerel, cobia and trevally.
There is a public mooring at Outer.
