A Brisbane family was left outraged when a security guard tried to force them off a public beach, claiming that a nearby Tangalooma resort held exclusive rights to the land.

Lisa Wilkins was swimming at the beach with her partner and daughter on Good Friday last month when she was approached by the security guard at the resort’s request.

The resort is built on Crown land and the Department of Natural Resources, Mines and Energy confirmed the beachfront is a public space.
