"Half Moon Bay receives its name from its crescentic shape. The 350 m long bay faces north in the southern corner, then swings around to face west along the northern section. Due to the partially protected nature of the bay, it has long been a site for boating. It has a boat launching ramp, a 100 m long jetty, and off the jetty are the remains of HMVS Cerberus which was grounded in 1926, to provide additional shelter for the boats.The beach is relatively protected in the southern corner and extensive sand shoals lie off the beach, necessitating the need for the long jetty."
