Land and air search for missing woman Nicole Barrenger from Sisters Beach, Tasmania

A large-scale search is underway for a missing woman whose car was found at a boat ramp at a beach in Tasmania’s north.

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.

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