A Victorian walker missing in the snow-covered Tasmanian wilderness survived for more than a week after losing his pack, which contained most of his supplies and his emergency radio beacon, police say.

Police spotted Melbourne man Michael Bowman, 57, from the rescue helicopter shortly before 4:00pm on Tuesday.

He was flown to Hobart where he gave the thumbs-up to waiting media.

When asked how he was feeling, he replied: "Thank you, fine, beautiful."

He will stay overnight in the Royal Hobart Hospital, where medical staff say he is in a stable condition and not suffering hypothermia.

A search began on Monday after Mr Bowman failed to return to the Cradle Mountain-Lake St Clair Visitor Centre from a bushwalk on Saturday.

Mr Bowman set off on July 3 and had planned to walk in the Mount Cuvier region.

The alarm was raised by his next of kin on Saturday after he failed to contact them.

Senior Constable Kristy Eyles said he had set up camp at Mt Cuvier in the Cradle Mountain-Lake St Clair National Park, and set off for a short day walk.

He had become separated in thick fog from his pack, which also contained his emergency beacon, accounting for why it had not been activated.

He spent a night exposed in "very cold" and snowy conditions, before managing to trace his footsteps back to his tent.

Senior Constable Eyles said Mr Bowman had been in his tent — where he had left limited supplies including some food and a sleeping bag — for nine or 10 days since.

"This is a great reflection of Mr Bowman's experience and skill that he has made it back to his tent, he's done the right thing and he's waited there to be rescued in the most likely spot for a rescue which has allowed us to have an excellent result today," she said.

Senior Constable Eyles said Mr Bowman was found in an area with rugged terrain and chest-deep snow.

"Without the experience that he's had in alpine environments in Victoria and on other wilderness trips in Tasmania, it's likely that we'd have a very different outcome," she said.

"It's the best result and we'll all sleep a lot better tonight knowing that Mr Bowman is tucked up safely in his bed."

Police had been unable to search the Mt Cuvier area until Tuesday due to weather conditions.

His rescue has been one of several in the Cradle Mountain-Lake St Clair National Park in the past 48 hours.

WA family reunited after night in the cold

Earlier, a West Australian teenager and her father made it to safety after becoming stranded in thick snow in the same national park.

Emily Koziniec, 15, and father Terry encountered severe weather two days ago and were forced to camp out on a track in snow again last night.

The duo was found safe and well about 1 kilometre south of Pelion Hut on Tuesday afternoon, but severe weather prevented a rescue helicopter from landing and rescuers set out on foot to reach them.

Terry Koziniec said the conditions were tough.

"I think we were prepared for where we were going but it was rough and it was such slow going," he said.

"The cold and the wind and the rain wasn't really an issue, but the track between the huts that was meant to take three hours, pretty much took three days.

"The big issue that we had was just a lot of fallen trees."

He said at some points they were trekking through waist-high snow.

"We had snow shoes but it was so thick," he said.

On Monday, two bushwalkers were airlifted from the Lake St Clair end of the national park.

On Tuesday an overdue walker from the UK and a Hobart school group were evacuated safely from the Cradle Mountain end.
