Police are appealing for public assistance to help locate missing woman Katie Fitzgerald.
The 40-year-old last made contact with someone yesterday just before 2pm.
It is believed Ms Fitzgerald is driving her silver Mazda CX7 and is known to frequent the Eildon, Hampton Park and Berwick areas.
It is also believed she could be off-road in the Gembrook or Cockatoo areas.
Police and family have concerns for her welfare as it is out of character for her not to make contact.

Anyone who sights Ms Fitzgerald or anyone who may have seen her is urged to contact the Cranbourne Police Station on 03 5991 0600.
