A new search is about to begin for the bodies of two men allegedly murdered 25 years ago while working as drug crop guards in Queensland.
Robert Grayson, 26, and Derek Van Der Poel, 23, were last seen alive in Gladstone in May 1993.
The pair had been guarding marijuana crops for Russell James Williams, 51, who is accused of killing them.
On Monday police said Williams had also been charged with trafficking in dangerous drugs, adding to his existing charges of two counts of murder, and one count of producing dangerous drugs.
He's due to face the Gladstone Magistrates Court on April 10.
Police last month searched the Kroombit Tops National Park, southwest of Gladstone, for the men's bodies but found nothing.
A new search is planned for Wednesday and Thursday, and detectives remain confident their remains will be found.
A $250,000 reward remains in place for more information about the murders.
