THE search for missing British-Australian man Gary Tweddle in the Blue Mountains is entering its second night, with local authorities launching a full-scale search for the Sydney local.
Mr Tweddle, 23, went missing from the Fairmont Resort near Leura in the early hours of Tuesday morning after attending a function. After being separated from a group of friends, Mr Tweddle made contact via telephone to indicate that he was lost before either his battery was depleted or he lost service.
Mr Tweddle was born in the United Kingdom, growing up in Berkshire before relocating to the Gold Coast as a teenager. He moved to Sydney several years ago to pursue a career in business, and currently lives in the North Shore suburb of Cremorne.
He is described as having short brown hair, brown eyes, a fair complexion and around 165-170cm tall. Mr Tweddle was wearing a checkered shirt, a black jacket and blue jeans at the time of his disappearance.
Temperatures in the Blue Mountains have been dropping into single digits overnight, with a low of zero degrees and possible snowfall expected for Sunday. Mr Tweddle is described as physically fit, with friends claiming that he would be well equipped to survive for a period of time in the bush.
Last year 18-year-old British backpacker Sam Woodhead went missing from a rural station in outback Queensland. He survived for three days in the harsh environment by drinking capsules of saline solution from his contact lenses.
