The British backpacker who went missing in the Australian outback for three days and was "hours away from death" told ITV's Daybreak he reached "a desperate point" where he either wanted to be saved or succumb to the harsh conditions.
Sam Woodhead, 18, said rescue helicopters missed an SOS sign he had made from his rugby shorts and thought to himself on the third and final day he was missing, either "pick me up now or do me in."
Speaking from Daybreak's studio in London, Sam's father Peter said it was a "great strategic move of yours not to unpack the contact lens' from your bag two months ago."
The backpacker drank contact lens solution in a bid to stop himself from dehydrating.
His sister, Rebecca, said she expected a "great birthday present" from him and added that her promise of giving her brother a whack "still stands."
Sam Woodhead became lost after going out for a jog from the Queensland cattle station where he was working.
The 18-year-old lost two stone in weight and survived the blistering 40C heat by drinking contact lens fluid and his own urine.
Woodhead said: "It was a really amazing feeling to be picked up and realise that I was actually going to make it through...and it wasn't going to be the end."
Claire Derry, Sam's mother, said: "His birth was one of the best moments of my life, and this is pretty close to it, getting him back again, because I was pretty convinced it was touch and go. I did an awful lot of praying during that flight."
