Police Commissioner Col Blanch said the teen had phoned Triple Zero informing them he planned to commit "acts of violence".
Blanch said a second Triple Zero call was made by a member of the public who allegedly witnessed the teen running around the car park wielding a knife.
"Two officers drew their tasers and one of the officers drew his firearm," Blanch said.
"They challenged the male to put down the knife, which he did not comply.
Blanch said officers deployed two tasers but neither had "the full desired effect".
"The male continued to advance on the third officer with the firearm, who fired a single shot and fatally wounded the male."
The offender and the victim were not known to each other.
Blanch said the 16-year-old was known to police and had both "mental health issues and radicalisation issues".
