UPDATE: STRANDED visitors on the Tasman Peninsula cut off by Tasmania's bushfires are being escorted out of the area by police.

Five convoys, totalling around 395 cars and 750 people, have moved out of the Nubeena area in the past 24 hours.

Resupply convoys of essential supplies have been escorted into the area with the arterial Arthur Highway remaining closed.

Police say about 500 cars and 1500 people remain at Nubeena, on the west coast of the peninsula, which has served as a haven for thousands during the fires.

Further convoys will be organised throughout today if conditions allow.

"A priority for police is to open the Arthur Highway as soon as possible," a Tasmania Police statement said.

"It must be remembered that the fire in the area remains active and uncontrolled.

"Police understand the frustrations of property owners who have been unable to return to their properties and are working to expedite their return to residences that are intact."

Police said inbound convoys were not available for members of the public.

Meanwhile, more than 550 houses have been searched and no bodies found despite concerns for around 100 people still unaccounted for.

A second round of more comprehensive searches is expected to begin later today with a contingent of Victorian police arriving to help.

"It's vitally important that all people who were in the area at the time, and are OK, self-register their details with the National Registration and Inquiry Service operated by the Red Cross," Acting Deputy Commissioner Donna Adams said.

"This will enable us to put the minds of concerned family and friends at ease and enable us to prioritise our search activities."

Some residents on the peninsula have been urged to seek refuge ahead of a renewed threat across the region.

The Tasmania Fire Service says residents in Eagle Hawk Neck, Pirates Bay, Doo Town, Old Jetty Road and Blowhole Road should move to the Tasman Civic Centre in Nubeena ahead of "expected fire behaviour".

Strong wind gusts of between 30-70km/h were expected to sweep across the state's south between midday and 3pm.

Around 40 bushfires continue to burn across the state, with concerns also held for uncontrolled blazes at Montumana in the northwest and Lake Repulse in the Derwent Valley.
