Mystery Surrounds Elderly Man Missing In Freezing Victorian Ski Fields

The search has ramped up to find a 72-year-old Victorian man whose car has been found abandoned in the state's alpine region.

The search to find Conrad Whitlock has ramped up as police hold fears for how much longer he can survive in the freezing temperatures.

Whitlock was last seen about 11.30pm on Monday at his Sandhurst property and is believed to have arrived in the ski fields about 6am on Tuesday,

His white BMW was found abandoned, about 200km from his home, on Mount Buller Road using smartphone technology as he'd left his mobile, keys and other items behind.

"It was a simple procedure for one of the employees to track the phone which alerted police to go and search the road and sure enough, there was his car. No sign of Conrad whatsoever," Inspector David Ryan told Seven's Sunrise on Thursday.

Police and family members are concerned for his welfare given his age and the fact that it is unusual for him to be at the ski fields.

"Time is of the essence in the search for Conrad," the senior officer said.

"Unfortunately, the conditions overnight are sub-zero temperatures and cold wet terrain. It is very steep, rugged country.

"This causes us to have significant concerns for Conrad's ability to survive many more nights."

While there are no concerns of foul play at this stage, police are investigating whether Whitlock suffered a medical episode, became disorientated and wandered off.

Police are urging anyone who knows if he left the area with somebody or has seen him to call Crime Stoppers on 1800 333 000.
