Police have called for witnesses who might be able to shed some light on how an 11-year-old girl fell to her death from a remote cliff in the state's south-east on Friday afternoon.
The girl, from Victoria, was with a large group in the Sand River conservation area at Buckland when she fell about 10 metres.
Acting Inspector Michael Foster said it was understood the group were climbing when the tragedy occurred.
However, the exact circumstances surrounding the fall remain unknown.
"I believe the group were climbing. But at that stage I am not sure what was happening," he said on Saturday.
"Whether she was just walking and lost her footing, it's still a matter for the [coroner's] report."
The girl had been holidaying in Tasmania with her siblings.
It is understood her parents, who were notified of the death on Friday, remain in Victoria.
In other news:
Acting Inspector Foster said it was a tragic situation for all involved.
"It's horrific. It's horrific at anytime of the year, but around Christmas holidays it's even worse," he said.
"Our thoughts are obviously with the families. It's just tragic."
Emergency services were notified of the incident about 2.20pm.
The Westpac Rescue Helicopter and police units from Sorell and Orford responded to the scene, which is not accessible by road.
CPR was administered, but the girl died at the scene.
The region was uncovered as a climbing destination about 2017 and has since offered about 150 named and traversed routes through the area.
Rock climbs on the routes range from 10 to 30 metres high.
Police would like to speak to anyone who might have been in the area or who witnessed the group of climbers.
Anyone with information can contact Tasmania Police on 131 444 or Crime Stoppers on 1800 333 000.
