Police investigating the disappearance of a woman almost 12 years ago will search bushland in a fresh bid to find her remains.
Lorrin Whitehead, from Bannockburn, vanished in February 2013 and has not been seen since.
The new search in Shelford, west of Melbourne, is based on intelligence that Ms Whitehead's remains could be in the area.
Police have not disclosed what information led to the new search, but said they were investigating all possibilities relating to her disappearance.
Ms Whitehead was last seen on CCTV at a local supermarket in Bannockburn just before 5pm on Friday February 8, purchasing a bottle of water, a card and a pen.
The mother of five was 42 at the time.
About the same time as her supermarket visit, a witness reported seeing Lorrin get into the driver's seat of a red 4WD in Bannockburn's CBD.
This was the last confirmed time she was seen by anyone.
Her work phone was found at her home after her disappearance and she has not accessed her bank accounts since.
A second witness reported seeing a red 4WD parked on the nature strip of Lorrin's property over the weekend of her disappearance.
At the time of her disappearance, Ms Whitehead did not own a red 4WD.
Last year, Victoria Police called for anyone with information about that red 4WD to contact police, it is not known if that call for help has sparked Tuesday's search.
Detective Sergeant Steve Murphy said Ms Whitehead's disappearance has remained a mystery.
"There are a number of aspects to her disappearance that remain extremely concerning for investigators," Det Sgt Murphy said on Tuesday.
"The area for today's search is not one that people will regularly walk through, so we're hopeful there may be some sign of Lorrin here even after all these years."
He reminded anyone with any information about Ms Whitehead's disappearance to contact Crime Stoppers.
