A British man has had a lucky escape after he was forced to call for help on his mobile phone when he got lost in the Australian outback for three days.
Three helicopters were scrambled and park rangers were dispatched to search for Martin Lake, 50, who set out for a walk in Alice Springs on Sunday.
He was discovered "dehydrated and sunburnt" in the rough terrain north of the town after calling the police.
A police spokesman said the man, from Merseyside was "extremely lucky."
When the British holidaymaker contacted police on Tuesday he could not tell them where he was, so it took rescuers four hours to locate him.
"This was an extremely difficult situation, as we had no idea where the man might have wandered," added the police spokesman.
Mr Lake told reporters in Australia: "I don't think I could have lasted another day out there. I feel a bit daft."
He spent three days dressed in a black T-shirt, shorts and flimsy footwear with neither a hat nor sun cream, a small amount of water, and the battery on his mobile phone was running low.
A search was launched involving helicopters, park rangers, police officers, volunteers and Aboriginal trackers.
