Acheron Island is one of the islands south of the Great Palm Island group.

The island lies near the border of Halifax Bay and Coral Sea, east of Rollingstone and north of Townsville about 40 km (25 mi).

The island is just north of Rattlesnake Island, where the RAAF practices bombing raids.

Possibly (covered up by SQN 3 Co WC Brown, at the time) the site of an accidental practice bombing with a Mk84 500 lb bomb by a RAAF FA-18 flown by a RAF exchange pilot in 1997.

Four campers were on the island and a large fire was started.
