Thetford reef is made up of numerous coral bommies where you can experience some very exciting wall dives and many swim throughs.

This reef is home to many soft and hard corals like staghorn and plate coral and an abundance of marine life. Look for the giant clams, butterfly fish, damsels and angelfish. Access to the reef is very weather and tidal dependent.
