During the robbery, which happened on Thursday, December 8 2011, two men wearing balaclavas threatened a female shop attendant with a long-arm firearm before leaving the store with about $280 in cash.

Police would like to hear from anyone who knows the whereabouts of Travis Shane Carman, who they believe may be able to assist them with their inquiries.

Police believe that Mr Carman is currently living in Western Australia and may be working as a shearer in towns close to Perth, possibly at Bindoon.

He is believed to be staying in the Caversham area when not shearing. He is described as fair skinned with blue eyes and very short cropped hair. He has a large tattoo covering his right bicep and shoulder which has barbed wire underneath.

Detective Senior Constable Wayne Ryan from the Warrnambool criminal investigation unit said he suspected that someone in the local community may know the whereabouts of Mr Carman.

“I urge any person with information to contact Crime Stoppers on 1800 333 000,” he said.
