Detective Bryan Anthony Swift is accused of providing the name and address of the suspect to the media, as well as information about a forthcoming counter-terrorism raid.
The 52-year-old is charged with two counts of misconduct in public office and one of communicating or publishing protected information.
Brisbane magistrate Michael Quinn on Friday committed Swift to stand trial in the district court on a date still to be set.
"I am satisfied there is sufficient evidence upon which a jury properly instructed could convict the defendant of an indictable offence with which he is charged," he said.
Mr Quinn said there was evidence of phone calls between Swift and a journalist, whose name cannot be published for legal reasons, and evidence of what was occurring at the time within the news organisation where the media representative worked.
The court also had footage showing the news organisation at the house during the raid.
"It is evident that they are the only media in attendance and the report identifies that it is an exclusive," he added.
Mr Quinn said what information was in the public domain at the time "is an important issue", but a matter for the jury.
During a committal hearing last year witnesses were questioned about an apparent plan to use the media in an attempt to gather intelligence in June 2018.
The strategy involved distributing CCTV footage via a media release, partly in the hope of prompting discussion by the person of interest that might get picked up by surveillance equipment, the court was told.
It also allegedly included sending a reporter to the man's home south of Brisbane after the CCTV vision had been released.
Detective Sergeant Michael Cameron told the hearing Swift floated the possibility of media attending the man's address in an attempt to "generate conversation".
"It was a proposal, there was no detail about it ... I didn't put too much weight on it," he said.
Text messages between two officers involved with the homicide investigation, exchanged prior to the reporter's visit, were also read before the court during the hearing.
They allegedly include discussions about media attending the house, and each party agreeing they were OK with it.
Allegations of media leaks were levelled at Swift following a Crime and Corruption Commission investigation.
Mr Quinn said in handing down his decision on Friday that much had been said recently about the role of the CCC in prosecutions like this one.
"It is to be understood that the CCC is not the prosecuting authority in these proceedings," he added.
"That is the role of the Office of the Director of Public Prosecutions, a body totally independent of the CCC and a body which exercises that independence fiercely."
