Emergency crews continue to search for a Canadian man who has been missing for more than a week in atrocious conditions in the NSW snow country.
The 25-year old, who is yet to be named by police, left his rental car at Charlotte Pass Village on May 13, intending to go bushwalking on Mt Kosciuszko.
"We do have serious concerns for this fellow's welfare," Cooma police Inspector Peter Rooney told ABC radio on Tuesday.
"No one has seen or heard of him since last Monday evening and in the area that he's been we don't know how equipped he is or how experienced he is in alpine trekking.
"For most of the week it's been fairly atrocious. There's been a number of days where there has been blizzard conditions. (On Monday) visibility was down to basically zero."
A search and rescue team of more than 20 will be expanded on Tuesday, and is being assisted by a police helicopter, Insp Rooney said.
"We only have fairly scant details from a flatmate in Queensland and another friend," he said.
"We know that he was intending to drive to Melbourne to be in Melbourne last Wednesday and once he got to the mountains he was intending to walk to Mt Kosciuszko and that's all the information we have at this stage."
Conditions in the mountains are forecast to be clear and cold on Tuesday, but Insp Rooney warned they could quickly change.
A Facebook page names the missing man as Bond University law student Prabhdeep Srawn, who has been living in Australia for about two years.
Originally from Hamilton, Ontario, Mr Srawn is a member of the Canadian Armed Forces and has some bushwalking experience, friend Tej Sahota said from the United States.
"It is not like him to go missing. He is experienced and very meticulous about timings," Dr Sahota told Fairfax Media.
A Facebook page titled "Help, Find Prabh Srawn - Missing Bushwalker", which includes a video montage of the smiling young man, has attracted hundreds of likes since its launch on Tuesday morning.
