Sydney teen Oliver Johnston died from head injuries after attempting Thredbo’s High Noon trail

Details have emerged about how a former private school boy died while skiing at a popular resort.

Sydney teen Oliver Johnston, 18, had been on the the High Noon run at Thredbo ski resort when he lost control and was launched head-first into snow gum trees on Sunday.

Thredbo is a popular ski village in the Snowy Mountains, south NSW. Olivier had been on one of the highest and steepest ski slopes when the accident happened.

The teenager was treated at the scene by emergency services but he was unable to be revived.

‘He was unconscious the whole time, from the moment he was taken off the mountains to when he was conveyed to the medical centre,’ a medical source told The Daily Telegraph.

‘He was wearing a helmet, but sadly, sometimes, that isn’t enough to save you, it’s the immediate stop that causes the most damage on impact.’ 

The difficult High Noon trail runs along the front side of the A-Basin from the top of Black Mountain Express to the Base Lodge.

Conditions were sunny with high visibility on the day of Mr Johnston’s accident.

Emergency services received a call to Mr Johnston’s location at about 11am and transported him to Thredbo Medical Centre at the base of the mountain but he was declared dead at the scene. 

Mr Johnston’s ‘inconsolable’ parents travelled from Killara, on Sydney’s north shore, to identify his body at Canberra Hospital.

‘One of his friends stayed at the medical centre and was praying he’d pull through, it was very sad for everyone,’ the mountain medical source said.

‘Our hearts go out to his family.’

Police are still investigating the circumstances of Mr Johnston’s death. 

Inspector Keith Price at Monaro police station said Mr Johnston had been skiing with a group of friends before he decided to try the High Noon trail.

‘He hit a spur in the ground and lost control, it threw him off balance and he veered into the trees,’ Mr Price said.
