A man is dead after being shot twice by police at Kippa-Ring, north of Brisbane, following reports of a number of hoax triple-0 calls.

Two male officers went to a house on Elizabeth Avenue about 1am (AEST) after tracing the hoax calls.

It was the third shooting involving Queensland Police Service officers in as many months.

Superintendent Michael Brady said the situation immediately turned violent and the officers opened fire after the 33-year-old suspect lunged at them with a knife.

"That has resulted in him being shot twice [and he] succumbed to his injuries," he said.

Superintendent Brady said the officers involved in the shooting were in shock but were otherwise unharmed.

"Obviously it's very traumatic for all those involved," he said.

Queensland Police Union general president Ian Leavers said he believed the officers involved were wearing body cameras which captured the incident and would be used in the investigation.

"As a police officer you never know what is about to confront you but we have a duty to investigate to ensure safety," Mr Leavers said.

"As we know things have unfolded but that's the difficult and dangerous nature of police work.

"We don't know what's about to confront us and we make instantaneous decisions but that's part of police work unfortunately ... and as we know there may be many who go over this for months, scrutinise the actions of police but we're used to that, that's how we operate."

Mr Leavers said officers tried to use the least amount of force possible, citing the peaceful G20 summit held in Brisbane over the weekend.

"But we do have a Taser and a firearm [and] when it comes to preservation of life, we will do whatever we can," he said.

"My view is every police officer is entitled to go home at the end of their shift to their family.

"It's concerning ... there are people out there who go to extremes. We simply have to do our jobs to protect ourselves and others."

Mr Leavers said the union would support the officers involved with both legal and emotional support.

"We're not robots. These types of incidents to take their toll on police."

Police were interviewing other residents who were inside the home at the time.

The street is home to a cemetery and just a few hundreds metres away from Kippa-Ring State School.

Forensic police were spotted inside and around the property this morning.

The Police Ethical Standards Command and the Crime and Corruption Commission were investigating.

Last month, a man was shot in the head and arms by police investigating the theft of a trailer and mower at Rochedale in Brisbane's south-east.

A month earlier, a gunman was shot dead by specialist police officers during a stand off at Inala in Brisbane's south.
