Rescuers in Tasmania have found a missing bushwalker alive and well after his fourth night lost in the Tasmanian wilderness.

Michael Bowman, 57, of Victoria, was hiking in the Lake St Clair region.

Tasmanian police said the Westpac rescue helicopter was transporting him to the Royal Hobart hospital for a medical assessment as a precaution.

Bowman had been expected to finish a walk at Lake St Clair visitor centre in the state’s central highlands on Friday.

The Bureau of Meteorology had warned he was at risk of hypothermia with cold temperatures and strong winds forecast on Tuesday night.

Several bushwalkers have been rescued from the Cradle Mountain area in recent days, including a British man and Hobart school group from Dove Lake on Tuesday.

A West Australian father and his daughter who became stranded by snow in the region two days ago were found safe and well.

They were reached by a search party on Tuesday afternoon and were flown by helicopter to safety.

Helicopter pilots are checking every hut on the popular Overland Track for bushwalkers who may be in trouble.

Bushwalkers including a Brisbane man aged in his 40s also had to be rescued on Monday from the north-west end of Lake St Clair.

Another two NSW hikers were plucked from the Walls of Jerusalem national park to the south earlier in the day.

People are urged not to go bushwalking unless they are well-prepared for freezing weather.

The temperature at Lake St Clair dropped to 2C overnight, with strong winds and rain expected to wash away the weekend snow dump.
