Paul Dubrovsky, 49, allegedly charged at police with knives during a dramatic confrontation on the Gold Coast overnight.

Mr Dubrovsky's mother, Wendy Watkins, said she twice called police after her son walked onto the street with two knives.

"I could hear [officers] saying all the time, 'drop the knives, drop the knives' — they said that 20 or 30 times," she said.

Ms Watkins said her son had been suffering from ongoing physical and mental health issues, which were compounded by a recent family tragedy and problems with alcohol.

"I'm no doctor, but I think he just snapped," she said.

"I think everybody's got a point where enough is enough and the system just breaks down, and I think this is how this has happened."

Officers were called to Wentworth Avenue at Molendinar about 10:40pm on Monday after reports an armed man aged in his 40s was causing a disturbance on the street.

Superintendent Mark White said officers shot Mr Dubrovsky up to six times in the torso.

Mr Dubrovsky remains in a stable condition in the Gold Coast University Hospital.

"Considering what was happening, they were excellent, they were doing their job — what else could they do?" she said.

"As much as I want to punch their lights out, you have to be aware of what was actually happening, and they're only human too."

A crime scene was set up on Wentworth Avenue as the Ethical Standards Command investigates the shooting.

Police charged Mr Dubrovsky with two counts of assaulting police, possessing a knife in public, and acts intended to cause grievous bodily harm.

Mr Dubrovsky is due to face Southport Magistrates Court on Wednesday.
