With no prior description of his vehicle, and no information the offender had left the Al Noor Mosque, the Armed Offenders Squad was powerless to stop him as he drove away.

Police Commissioner Mike Bush said the public should have as much information as possible about the response, and the timeline released today provided further clarity.

"I want to emphasise we are still in an investigation phase and now a prosecutorial stage.

"The investigation team continues to be focused on confirming certain details, particularly timings sourced from a number of electronic systems and devices with differing internal clocks. The information released today is currently the best information I have to date and what I can release without compromising the criminal investigation or the trial."

Mr Bush said police staff acted "as quickly as humanly possible given the rapidly unfolding nature of the event, and the information available to us in that very brief period of time".

"I reaffirm my previous comments that police staff acted as quickly as humanly possible given the rapidly unfolding nature of the event, and the information available to us in that very brief period of time," Mr Bush said.

"As part of normal operational practice we are debriefing our response. In order to provide absolute transparency this will be done by an independent team, including a Queen's Counsel.

"The debrief is an important process to ensure any lessons are learnt, and used to inform future operational responses."

Mr Bush said police have begun to transition from the protective security measures that were in place following the attack.

"Generally this means frontline staff will transition back to our normal approach regarding carriage and access to firearms," Mr Bush said. 

"You may still see some frontline staff continue to carry firearms on a case by case basis if particular circumstances necessitate this approach.

"We will still maintain our tactical capability to respond to incidents as required, however the public can now expect to see fewer police officers routinely carrying firearms."

Mr Bush said police officers from Australia and Hong Kong, as well as Defence Force personnel, provided initial first aid to victims at the Linwood mosque, alongside police staff.

"Their specialist skills have been credited with saving lives and we were fortunate to have them on the ground with us."

Police have also released a map of the alleged shooter's movements.
