A $500,000 reward is on offer to solve the case of a young Indigenous mother's disappearance from Queensland's remote Cape York more than a decade ago.
Mother-of-two Allison Bernard disappeared after a night out at a hotel in far north Queensland in February 2013.
The 23-year-old had been at the Exchange Hotel in Coen before disappearing between the nearby Archer River and her hometown Kowanyama.
Queensland police conducted a large-scale search of the area but no trace of Ms Bernard has ever been found.
An inquest last year was told the last person to see Ms Bernard was quarry caretaker Thomas Byrnes, who denied any involvement in her disappearance.
Ms Bernard is described as Indigenous, 155cm tall, with a slim build and brown hair.

"We will not give up. Ms Bernard's disappearance has had a devastating impact on this community and together we won't stop until we find answers," Supt Smith said.
"We would like to thank the local community who continues to support our ongoing investigations and urge members of the public to continue spreading the word – anyone with information should immediately contact police."
