Aubrey Donahue was killed by specialist officers following a four-hour siege at a home in Mareeba, west of Cairns, on Saturday afternoon.
Officers were called to a Mareeba home at 11.30am in response to an incident, where a 27-year-old man was allegedly threatening self-harm, and not allowing a woman to leave the home.
It is alleged the man was armed with a knife when he advanced on specialist officers at about 3.30pm, before he was fatally shot by police.
Queensland Police said CPR and first aid was delivered, but he died from his injuries at the scene.
Dozens of people gathered outside the Mareeba police station to express their distress and anger about the shooting, many holding flags demanding "Justice for Aubrey".
Mr Donahue's mother, Desley Ketchup, was one of those at the protest and said she wanted answers into the circumstances of her's son's death.
"This is about justice for my son," she said.
"We are hurting, we are angry, and we want justice now."
Social worker and family friend Isobelle Anderson echoed the concerns.
"Why did they have to shoot him?" Ms Anderson said.
"Why didn't they taser him?"
A community meeting was also held in the town on Sunday, that was attended by around a hundred people, including senior police.
The fatal shooting is now the subject of an ethical standards probe, on behalf of the coroner.
Police Acting Superintendent Sonia Smith said forensic investigations were also ongoing.
"Circumstances surrounding this incident are being investigated by independent officers from the Ethical Standards Command on behalf of the state coroner," she said.
"The matter is also being overviewed by officers from the Crime and Corruption Commission.
"The investigation will take as long as it needs to take to ensure it is independent, transparent and provides answers for the man's family and for everyone involved in this matter."
