Urgent land and air search launched for missing woman after her abandoned car was found at a boat ramp at Sisters Beach in northern Tasmania

An urgent land and air search is underway for a missing woman whose car was found left at a boat ramp at a beach in Tasmania.

Nicole Barrenger, 45, has not been heard from since Tuesday.

Police have been searching the Sisters Beach area where she lives, about 87km west of Devonport in the state’s north-west.

A large-scale search intensified on Wednesday after officers discovered her vehicle at the Sisters Beach boat ramp.

The boat ramp at the end of Irby Boulevard is mostly used by recreational fishermen.

There are serious concerns for Ms Barrenger’s welfare.

Authorities have deployed multiple police units and ground crews, including the police dive squad and Surf Life Saving Tasmania.

The Westpac Rescue Helicopter from Melbourne is helping in the search.

Ms Barrenger is described as having a stocky build with shoulder-length red hair.

Anyone with information regarding her whereabouts is urged to call the police on 131 444.
