NSW Police

NSW Police said the man from Queensland was shot dead by a senior police officer inside Westfield Bondi Junction on Saturday afternoon, after setting upon several people inside the complex with a knife and triggering an evacuation.

Six people were killed, including four women and one man who died inside the centre, and another woman who died in hospital.

The boy was pulled over in Broken Hill in the New South Wales outback on Saturday after a patrol noticed the car's bumper dragging on the ground.

Police said the boy had been attempting to drive 4,000km from Kendall in NSW to Perth, Western Australia.

He was arrested and taken to Broken Hill police station.

His parents, who had reported him missing, picked him up on Sunday.

"He'd taken the family car," Det Insp Kim Fehon told the Australian Associated Press.
