Heartbreaking detail at vigil of slain police officers

A policewoman who survived a deadly shooting at a rural property in Queensland has paid tribute to the victims at a candlelight vigil.

Constable Keely Brough stood with members of Queensland Police at a memorial in Chinchilla on Friday night, honouring Constables Matthew Arnold, Rachel McCrow and resident Alan Dare.

The trio were gunned down during an ambush at a rural property at Wieambilla, about three hours west of Brisbane, on Monday.

Constable Brough and her colleague Randall Kirk escaped the ordeal with minor injuries.

Killers Nathaniel, Gareth and Stacey Train died in a subsequent firefight with heavily armed tactical officers.

Hundreds of people held candles at the gathering on Friday and lined a street to form a guard of honour for police and ambulance officers.

Queensland Assistant Commissioner Charysse Pond read out a message from Constable Arnold's family, thanking members of the public and police for their support.

A fundraiser for the widow of Mr Dare had raised more than $77,000 by Saturday morning.

A funeral service with full police honours will be held in Brisbane for the fallen officers on Wednesday.

Killers posted disturbing video admitting to shooting police

The show of solidarity came after it was revealed the armed assassins involved in the shooting uploaded the names of individual police officers to conspiracy websites days before the deadly confrontation.

The disturbing posts from the killers prompted calls for a security review for police.

Video from a deleted Youtube account shows a couple, believed to be Gareth and Stacey Train, admit to the killings.

"They came to kill us, and we killed them," the man says.

However, in an earlier video, posted on December 8, Gareth Train names individual officers from Queensland and NSW including contact details, stations and phone extensions.

The police union has called for security to be reviewed amid concerns of reprisal attacks and officers holding genuine fears for their safety, sources told AAP.

Police continue to probe the Train brothers' online activities, including their involvement in extremist conspiracy groups and forums.

Home Affairs Minister Clare O'Neil said security agencies were actively considering the implications for national security.

She said conspiracy theories and disinformation were being "turbocharged by technology into terrible acts of violence".

Opposition Leader Peter Dutton, a former Queensland police officer, likened the killers to Islamic extremists and raised serious concerns about online radicalisation.

The head of the Australian Security Intelligence Organisation, Mike Burgess, previously expressed concerns with the rise of online radicalisation.
