A seascape painting of Sellicks Beach in South Australia. Sellicks Beach is only 53 km from Adelaide. It is a beautiful, and often deserted beach. The big, prominent hills of Sellicks Hill Range roll down towards Gulf St Vincent and the broad sandy beaches run north towards Adelaide. Sellicks Beach is one of the few beaches where parking is allowed on the sand and it’s as popular with families for its safe swimming as it is with surf fishermen.
