THE family of a missing man who worked on a pipeline near Biloela are asking for help in finding him.
David Josifovski was last seen on Friday, July 11, when he was dropped at Perth airport at 6.30am.
He didn't catch a plane to anywhere, and has not been heard from since.
His sister Brianna Robinson said he worked in Biloela for a couple of months and did trips into Gladstone on his days off.
"He's got friends and former workmates in the region, if anyone has seen him please contact Crime Stoppers," she said.
David is thought to be in Queensland and may have been spotted at Surfer's Paradise. Mr Josifovski is 25, has a crucifix tattoo on his arm with the Macedonian sun in the background and his whole back is distinctively covered with various tattoos with a graveyard theme.
He has not left the country, boarded any planes, and is not in any hospitals.
"His family are really worried, if you know where David is please call 1800 333 000," Ms Robinson said.
