The woman was attended to by an employee of one of the businesses at the ski village, who is also a volunteer ski patrol member, while they waited for an ambulance to arrive.

However, the ambulance got stuck on the road up to the mountain due to adverse conditions and the Westpac Rescue Helicopter was tasked to the scene.

The incident comes after it was revealed the Ben Lomond Ski Patrol, a volunteer unit that responds to injured skiers and rescues, was told by Parks and Wildlife their services wouldn't be required.

They were notified on August 14 they would no longer be required due to a clause that states the service isn't needed if the ski lifts are not operational. The ski lifts are closed due to lack of snow.

Ben Lomond Ski Patrol president John Marshall said a mid-week patroller would have been on site if the stand down orders had not been issued and would have alleviated the need for the helicopter.

"What happened is a standard ambulance waits at the bottom and then a four-wheel-drive goes to the top to transport the patient down, but the 4WD got stuck in the snow without snow chains," Mr Marshall said.

"Our mid-week patroller would have been there and we do have the resources to transport people down from the mountain, so it would have alleviated the need for the helicopter, which comes at a cost."

PWS notified the ski patrol on August 14 that its services wouldn't be required due to a clause in the Ben Lomond National Park Management Plan from 1998, that says the ski patrol is only needed when the ski lifts are operating.

However, Mr Marshall refutes that claim, saying the majority of incidents don't involve ski lifts.
