"The reality is if I hadn't phoned them, I don't think I would've made it through the night because it was pretty cold and there's no road access.
"It just doesn't bare thinking about."
Wearing only a merino top and leggings and with the last of the early evening sun setting, Alice spoke with Life Flight staff over the phone until, finally, they appeared with a roar overhead.
"I'd tried to stand up a couple of times while I waited, but my knee just wasn't working.
"It was such a relief when I saw the paramedic running down the track."
After being assessed and attached to a harness, Alice was winched up into the helicopter, where she was eventually wrapped in blankets and on her way to hospital, where she remained for 11 days.
Now, on bed rest and in a leg brace for 12 weeks, she encouraged others to make the phone call in a similar situation.
"I'm so thankful for Life Flight and how reassuring they were.
"At the time, I was really frightened by the prospect of being winched into the helicopter, but they were so calm and relaxed.
"It was very much business as usual for them."
