Detectives say she was assaulted by a stranger on New Year’s Eve at Thomson Bay between 10.15am and 12.30pm.
She was laying on a towel, wearing a black bikini with a white sundress over the top, while she was sunbaking on the popular beach.
Police say several people were in the area around the time of the incident, which took place north of the ferry jetty.
Anyone who remembers spotting the teen, or a man acting suspiciously, should contact Crime Stoppers on 1800 333 000.
