In the Gold Coast incident, the 29-year-old man, identified as Joshua John Kleeman, was shot at Bellagio Crescent at Coomera multiple times by as many as three officers.

In the second incident, at Stretton in Brisbane’s south, a 43-year-old man allegedly lunged at officers with a “large metal sharpening file” before he was shot twice by a single frontline police senior constable.

Police confirmed the man’s 41-year-old wife and four children had been able to escape the Brisbane home at Liquidambar Place around 7:00pm on Sunday, before contacting police.

Queensland Police Union President Ian Leavers said police had tried to negotiate with the man, but he allegedly advanced at them with a knife, was shot once, got up and continued to lunge at police.

Brisbane Regional Crime Coordinator Detective Superintendent Andrew Massingham said police officer shot the man a second time in the shoulder, then the man still attempted to throw the knife-like file at police.

Massingham said the wife had locked the man in the garage of the home after an escalating domestic incident, then she fled with the children into the garden and to neighbours and called police.

“What I can say is that man was intent and was highly motivated to cause injury to one of our officers,” Massingham said.

He said there was no domestic violence or mental health history and the motivations for the incident were unclear.

The man was taken to the Princess Alexandra Hospital in Brisbane in a serious but stable condition.

Gold Coast Superintendent Geoff Sheldon said earlier on Sunday around 3:20pm, police officers had gone to the Coomera, Gold Coast address to conduct a welfare check regarding social media posts indicating a man was potentially likely to self-harm.

Police allege the man answered the door to the three Coomera Police Station officers brandishing a knife.

Police allege he was asked several times to put the knife down.

Negotiators were called to speak to the man. However, he allegedly refused to drop the knife and rushed at police.

“All of a sudden he suddenly rushed into a number of the officers forming part of the cordon and they’ve opened fire and he’s been struck multiple times with gunshot wounds,” Sheldon said.

“Literally within seconds, our officers have turned from potential life takers to lifesavers and started applying tactical first aid to help him recover from his wounds,” he said.

The man was taken to Gold Coast University Hospital where he underwent surgery Sunday night. He remains in an induced coma and will undergo further surgery today.

It is unclear how many times he was shot or by how many of the officers.

Leavers said the incident was recorded on the police officers’ body-worn equipment.

Sheldon told ABC Gold Coast that immediately after the shooting, police officers applied first aid based on first-responder treatment for warzone casualties while emergency services rushed to the scene.

He said the battlefield emergency medical training may have prevented the shooting from being fatal.

“It’s been an interesting change in our whole training regime,” Sheldon said.

“We used to fix a cut or do something about a burn, now our first aid training is doing something for someone who has had a leg severed, someone with a gaping chest wound.

“We learned a lot from what our Army and Airforce people have experienced overseas in Afghanistan with some of the tactical first aid has to be done on the field with major incidents such as explosions.

“So now we’ve got the right equipment and the right training so we can apply an enormous quality level of medical aid right from the get-go.”

Both shootings are being investigated by the Ethical Standards Command. The investigation is subject to oversight by the Crime and Corruption Commission.
