A police officer had no choice but to shoot dead a radicalised Melbourne teenager who launched a stabbing attack on another officer, a coroner has found.
Numan Haider, 18, died instantly when shot in the head on September 23, 2014 after stabbing two counter-terrorism officers who had arranged to meet him outside Endeavour Hills police station.
"There was no time or opportunity for the officers to use a lower force to prevent further injuries," Victorian coroner John Olle said in his findings on Monday.
There were no adverse findings against ASIO, Victoria Police, or Australian Federal Police among Mr Olle's comment.
A Victoria Police officer and an AFP officer had arranged to meet Haider outside the suburban police station to assess his attitude and establish whether he was a threat to national security.
