The search for a missing Queenslander has shifted to a remote corner of the Northern Territory outback, more than two months after he was last seen.
Caboolture resident Peter English, 37, last made contact with family on February 11 while driving to Mount Isa, in western Queensland.
He drove alone in a dark-grey Ford FG Falcon sedan, with the New South Wales licence plate FPV-849.
While police initially said Mr English may have gone north to Mackay or returned to the state's south-east, they now believe he crossed the Northern Territory border.
Today NT Police said investigations suggested his car was last sighted in the Tennant Creek area and may have travelled south towards Ali Curung.
They did not say when this possible sighting took place.
Tennant Creek is 661 kilometres west of Mount Isa on the Barkly Highway.
According to a statement from police it is out of character for Mr English not to remain in regular contact with family.
Mr English is Caucasian, about 179cm tall with a solid build, fair complexion, brown hair and hazel eyes.
It's not known what spurred Mr English's trip or how the possible sighting in Tennant Creek came to light.
Police said he was unemployed.
Anyone with information on the whereabouts of Mr English and his vehicle is asked to contact Northern Territory Police or Queensland Police on 131 444 or Crime Stoppers on 1800 333 000.
