"An ambulance was called by another person on the beach and arrived a short time later, transporting Caroliah to hospital.
"Unfortunately no one got the details of the man responsible for saving Caroliah and we would love to be able to get in contact with him so he can be thanked appropriately for his actions.
"Caroliah's parents would also love to find this person and want to thank them personally."
Witnesses say that the man may have been of Indian descent but few other descriptions have been supplied to Police.
Police would like to hear from anyone who was present on the beach at the time or who may know the man or people responsible for saving the girl's life.
