A desperate search is back underway for a 19-year-old woman who went missing in the bush after becoming separated from her boyfriend on Wednesday.
The teenager was last seen at about 2pm on Wednesday after her partner lost sight of her on the Wedding Cake Rock Trail, south of Bundeena, New South Wales.
Police began a desperate search for the woman at about 5pm but it was suspended late last night. Rescuers set out again at 8am on Thursday.
At this stage police are not treating the case as a criminal investigation. It is not clear how the couple ended up separated.

The woman did not have any food or water with her when she vanished in the 58.3-square kilometre park south of Sydney.
She was last seen wearing a top, jeans and a brown scarf.
A police helicopter was used to search for the woman on Wednesday evening, as were officers on the ground.
The search was suspended just before midnight because of poor conditions.
The SES and a police dog unit are expected to join the search on Thursday.
Temperatures plunged to as low as 13C south of Sydney last night as rain set in.
