A 24-YEAR-OLD man has been shot dead by police after a violent stand-off involving a knife at Ipswich Train Station.
Queensland Police Union president Ian Leavers confirmed a report will be prepared for the coroner.
He said the officers involved were "simply doing their job" at the time and were "quite shaken" by the shooting, which happened at 4.15pm on Sunday.
Acting Superintendent Melissa Adams from the Ipswich District said three police officers were involved in a "very brief" confrontation before the shooting.
The man, who is believed to be from the Ipswich suburb of Riverview, had been standing on a station platform when the incident occurred, she said.
"Shortly after 4pm this afternoon, police had cause to attend the Ipswich railway station," Superintendent Adams said.
"They were confronted by a male person...that male person was shot by police and unfortunately that male person is deceased."
Superintendent Adams said investigations were at a very early stage and there were a number of witnesses on the station platform, who detectives needed to speak with.
She described the situation as a "tragedy" and confirmed police are still following up with the man's family.
Mr Leavers said police use their firearm as a last resort, but would not be drawn on if a taser had been used first.
Mr Leavers said the police officers involved had the union's full support.
"In incidents that are like this and where shots are being fired, it takes a tremendous toll on police and sometimes they never get over it," he said.
The Ethical Standards Command will investigate the incident.
The Courier-Mail understands the shooting happened just as a train pulled into the station, leaving commuters in the centre of the unfolding drama.
A police spokesman said no bystanders had been injured.
