A coronial inquest into the fatal police shooting of a man on the NSW Mid North Coast has found little could have been done to prevent his death.

Paul Lambert, 36, was shot three times during a six-minute stand-off with police on the Pacific Highway at Bonville, south of Coffs Harbour on November 3, 2016, following a high-speed chase.

The inquest last year heard that Mr Lambert lunged at officers with a knife, enraged after a taser failed to connect and subdue him.

Earlier that evening Mr Lambert had stabbed his ex-girlfriend, Angela Jay, 11 times and doused her with petrol at her Port Macquarie home.

Dr Jay managed to escape to a neighbour's house and Mr Lambert fled the scene and drove north.

Troubled relationship

Mr Lambert and Dr Jay had met in August 2016 on the dating app Tinder. The relationship was brief, after Mr Lambert became increasingly possessive and controlling.

Dr Jay told the inquest last year that when she tried to break up with Mr Lambert, he became suicidal.

"I felt like if he killed himself it would be my fault," she said.

"I felt trapped, I really wanted to get away from him, but I didn't know how."

The inquest heard Mr Lambert, who had been diagnosed with borderline personality disorder, had a history of threatening and violent behaviour against women.

Between March 2003 and October 2016, he was the subject of 10 interim or full apprehended domestic violence orders in relation to five women. On three occasions, he was charged and convicted in relation to the breach of an apprehended domestic violence order.

Mr Lambert was also in breach of parole and probation orders in Queensland at the time of the attack.

Police not to blame

Deputy state coroner Teresa Sullivan said if a warrant had been issued for Mr Lambert's arrest it was highly likely that his encounters with the NSW Police Force in October and November 2016 would have led to his arrest and, possibly, psychiatric treatment.

"An examination of the Queensland parole system is not suitable for this inquiry but I direct that a copy of the transcript of the inquest and of these findings be forwarded to the Queensland Probation and Parole," she said.

However she said, ultimately, the only thing that may have prevented Mr Lambert's death was for him to have saved himself.

"An AVO would not have stopped him," the coroner said.

The coroner praised police for their actions in trying to negotiate with Mr Lambert during the fatal stand-off.

During the furious six-minute stand-off, Mr Lambert asked officers "What do I have to do to get you to shoot me?".

"I do not consider there was any available alternative to lethal force when Mr Lambert was shot," Ms Sullivan said.

"I accept without reservation that [Senior Constable] Myles had an honest and reasonable belief that his life was in danger and that [Senior Constable] Buckley had an honest and reasonable belief that SC Myles' life was in danger when they discharged their firearms."

While accepting little could have been done differently, the coroner recommended that police continue to investigate the use of other options — including the use of shields — when dealing with siege situations where assailants were armed with knives.

She also asked that the NSW Police Force consider the implementation of an opt-in information sharing system to allow licensed weapons dealers to check if a person attempting to buy a knife has an outstanding apprehended violence order or apprehended domestic violence order.
