The Ipswich gunman who refused to drop his weapon before he was fatally shot by officers during a siege at the weekend has been identified as Tjay Doeblien.
Queensland police said they were called to a disturbance in Earnest Street in One Mile around 11:15am on Sunday, after reports of a man with a firearm threatening people at the location.
Around midday, an emergency declaration was put in place under the Public Safety Preservation Act, ordering residents of Earnest Street and Woodford Street to remain indoors.
Police attempted to negotiate with Mr Doeblien, who was armed with a handgun.
Police will allege officers were threatened before the man was shot around 12:30pm.
Paramedics and officers at the scene then administered first aid to Mr Doeblien, who turned 27 last Friday and was known to police.
Witnesses at the scene said they heard four shots fired.
The declaration was later revoked around 2pm.
Acting Assistant Commissioner Dave Cuskelly said on Sunday the man was shot after he exited the property while holding the weapon and refused to put it down.
An investigation by the Ethical Standards Command is ongoing, and a report will be compiled for the state coroner.
Ian Leavers said the Queensland Police Union was supporting the officers and their families.
Mr Leavers said the officers involved were males who had been in the force for under five years, and were under the command of a "very experienced district duty officer".
"They had called in other specialist units but obviously they weren't able to get here," he said.
'Split second decision' with lasting impact
Assistant Commissioner Cuskelly said the decision to shoot does not come easily.
"[Police] are trained extensively around that decision-making process, and it's extremely dynamic," he said.
"[They are] split second decisions that have got the ultimate consequences as we've seen, so they take it very seriously.
"It's really important that the police work very hard to find answers, specifically for the family of the man [who has] died and, also, all those attending police and emergency services people, because these tragedies are felt by everybody."
Tributes are being circulated on social media for Mr Doeblien.
Mr Doeblien's former partner said the father of three had battled mental health issues.
Colette-Lee Wilson said his friends and family were devastated by his death.
"He was a good person, just made the wrong choice in this moment," Ms Wilson said.
"We have to live with the consequences of his actions yesterday and there are so many people on social media [who] have no idea of what the circumstances were …'' she said.
