A $250,000 reward has been put up for anyone with information that leads to the arrest and conviction of those responsible for the suspected murder of Novy Chardon.
Police Minister Jack Dempsey and Gold Coast Detective Superintendent Dave Hutchinson are expected to formally announce the reward in Brisbane on Thursday morning.
The reward has been funded by the state government.
Missing Gold Coast woman Novy Chardon.
Indemnity from prosecution may be offered to any accomplice who offers information, but this will be at the discretion of the Queensland Police Commissioner.
Mrs Chardon was last seen at her Upper Coomera home on February 6, 2013. Her car was found abandoned near the Nerang train station five days later.
Police believe she was murdered and suspect more than one person was involved.
Last week, police spent three days digging up a Gold Coast hinterland backyard in search of a white ute that may be linked with the case.
Investigators eventually found a Ford F100 ute buried at the Mount Nathan home, but are yet to say whether the find has provided any leads.
The male occupant of the house has denied anything to do with Mrs Chardon's disappearance.
Mrs Chardon's husband, John Chardon, has been a person of interest in the case but has denied any involvement.
