A hiker has died after falling 40 metres during a climb at the Glasshouse Mountains on the Sunshine Coast, while two other men were injured in separate incidents.
The 28-year-old Currimundi woman fell onto rocks down the eastern side of Mount Beerwah just after 1:30pm on Saturday.
Her friend attempted to provide first aid, but paramedics pronounced her dead when they arrived.
Queensland Ambulance Service operations supervisor Leighton Allen said the woman's death was a tragedy.
"We just believe that both the patient and her friend were coming down the mountain on the eastern face and then somehow there has been a tragic accident there, which cost the poor patient her life," he said.
Earlier in the day, a man in his 50s who was parachuting suffered serious leg and head injuries when he fell 30 metres from Mount Beerwah.
Mr Allen said the man suffered "significant leg, head, and possible chest injuries".
He was taken by helicopter to the Royal Brisbane and Women's Hospital in a serious condition.
Meanwhile, a man in his 20s suffered a dislocated shoulder after slipping and falling about 10 metres just before 5pm.
Mr Allen said paramedics were still helping extricate the woman's body from the earlier fall, when they received the call about the third fall further up the mountain.
The man was taken by the LifeFlight helicopter to the Sunshine Coast University Hospital in a stable condition.
Multiple incidents 'extremely rare'
Mr Allen, who attended all three jobs, said about 30 "remarkable" emergency services personnel were involved in the weekend incidents.
"To have three that occur within that short time frame is extremely rare," he said.
He reminded people to only climb within their limits, and to avoid hot or wet conditions.
"Just think about the time of the day, especially during summer when it's obviously very hot and humid," Mr Allen said.
"It's not only the fact that you will get sweaty, it's also the rock face is very hot. That can cause you to not get a good grip, maybe burn your hand, then you'll slide and have an incident.
"So if you're going to climb … do it early in the morning, give yourself plenty of time to get up there.
"Don't — for any reason — try going late in the afternoon because darkness comes on very quickly and you can be stuck up there.
"It doesn't matter your experience … accidents still do happen."
Police will prepare a report for the coroner.
