John Chardon has been committed to stand trial over the alleged murder of his wife Novy five years ago.
Magistrate Penelope Hay ruled on Tuesday there was enough evidence for his matter to be heard before a Supreme Court jury.
It followed a five-day hearing in Brisbane that featured explosive evidence from convicted conman Peter Foster and a Filipino man claiming to be Chardon's lover.
Foster alleged Chardon made a jailhouse confession he shot his wife in the back of the head and dumped he body in the Southport Seaway, while the pair shared a jail cell in 2015.
He had not been charged with his wife's murder at that point and was incarcerated on other offences, while Foster had become a police informant in an attempt to get information on Novy.
Filipino man Marshall Bari Aguilor claimed Chardon asked him if he could kill after the pair had sex in a hotel room in the Philippines for the first time.
Aguilor said he asked Chardon who he wanted to kill.
"He said, 'My wife'," he told the court on Tuesday.
During the hearing, Chardon's defence barrister Tony Kimmins repeatedly questioned Foster and Aguilor about their ability to lie.
He also put to them they had drawn their own conclusions about things his client had said.
Novy was last seen at her Upper Coomera home on February 6, 2013, and her body has never been found.
Chardon, who entered a plea of not guilty on Tuesday after he was committed to stand trial, was charged with her murder in 2016.
