Police have released CCTV depicting some of the last known movements of a man, who has been missing from Cloncurry since November 20.
Jonathon Gray was last seen around 11.50am on the Barkly Highway, just north of Mount Isa.
Officers hope releasing CCTV of Jonathon at a post office on Simpson Street around 3:45pm on November 17, in the days leading up to his disappearance, could assist with locating him.
He is believed to be travelling in a white 2007 Volkswagen Jetta with a missing driver side front hubcap and Queensland registration 678YGD, similar to the one pictured below.
CCTV also shows that car travelling in Mount Isa just before 10am on November 18.
Police and family hold concerns for his welfare due to the length of time he has been missing, and his disappearance is out of character.
Officers are appealing for anyone with dashcam between Mount Isa and Camooweal, and Mount Isa and Cloncurry from November 20, to come forward to police.
Also, anyone who has business dealings working alongside Jonathon in the mining industry Australia-wide, who might know something about his disappearance, is also asked to contact police.
Jonathon is described as Caucasian, around 182cm tall, with a heavy build, with blue eyes and grey hair.
