A mother climbed down a 25m embankment and into a sinkhole to comfort her trapped daughter while her son went to call for help at the Honeycomb Caves at Chudleigh yesterday afternoon.
About 4pm, police and emergency services were called to a hiking accident involving the 15-year-old girl.
Police say that the girl was with her mother and brother hiking around the caves when she attempted to climb up a bank, slipped and slid about 25 metres into a sinkhole, before landing on a log, which partly blocked the hole.
The girl's mother managed to descend into the hole and remained with her daughter, while her brother called for help.
The girl and her mother were eventually winched from the hole by Tasmania Police and the SES, and were taken by ambulance to the Launceston General Hospital.
Police say the girl suffered possibly minor neck injuries while both were suffering mild hypothermia.
