A Queensland Coroner has recommended police should consider whether firearms training should happen more frequently than once a year.

It was among 19 recommendations made by State Coroner Terry Ryan after Queensland Police shot five men dead between August 2013 and November 2014.

They were Laval Zimmer, Anthony Young, Edward Logan, Troy Foster and Shaun Kumeroa.

The shootings happened in Brisbane and the Gold and Sunshine Coasts with three of the incidents occurring during one week in November 2014.

Coroner Ryan suggests a purpose-built facility to ensure police can explore ways in which use of force training can happen in low-light conditions.

Officers involved in fatal shootings would also need to undergo a mandatory psychologist or psychiatrist session independent of the police service.

Families of those shot by police and witnesses should be provided with counselling, according to recommendations mentioned.

A number of the recommendations focussed on increased mental health training for officers.

It is believed five of the men shot in the separate incidents suffered from mental health issues.

The mother of Laval Zimmer, who was in court for the findings, welcomed the move.

Police Union President Ian Leavers welcomed most of recommendations by the Coroner and said mental health was now the "core business of police."

Mr Leavers said it would cost hundreds of millions of dollars every year to implement all the recommendations and that 200 extra police would be needed to meet the increased focus on mental health.
