One teenager is dead and another is fighting for life after the pair fell while hiking in the Glasshouse Mountains on Queensland's Sunshine Coast.
It is believed they were part of a group of three who were climbing Mount Beerwah earlier today, when two of them, both 18, fell down rock face.
A teenage girl suffered severe injuries after falling about 60 metres and died at the scene.

A man believed to be her boyfriend fell about 90 metres and suffered critical head injuries.
He was airlifted to hospital after paramedics arrived and was taken to Sunshine Coast University Hospital, where he was fighting for life.
Search and rescue teams climbed up the mountain to ensure the safety of the other climber, who was uninjured but suffering from shock.
It is believed she is the sister of the teenager who died.

The mountain has been closed to the public for nearly a week after heavy rainfall in south-east Queensland had made the area unsafe for walking.
"This closure is a precautionary measure following high rainfall events," a statement on the Queensland Parks and Forests website said.
"The risk of large rockfall above the summit route is much higher after heavy rain."
There is signage in the area highlighting that the mountain is closed to the public.
The closure was set to be lifted tomorrow, but it is not known if it will now be extended due to today's accident.
