It's the latest attack in the CBD. Six people died in the 2017 Bourke Street tragedy, while one was killed in the Flinders Street incident in December last year. Mr Andrews, speaking at the Shrine of Remembrance on Sunday, said he wasn't going to "fundamentally change the way the city works by, for instance, not running any trams". "That wouldn't make any sense," he said. "We made significant efforts to make sure we fortified areas that were identifed by experts as points of weakness in our city knowing that we can never make every single physical space 100 per cent safe. Common sense tells you that." Mr Andrews said he'd been given no advice from experts that further work needed to be done, but he would have a "steely determination" to do more if necessary.

"Out of every incident there are learnings and that's an important part of the culture we've brought to this important task," he said.

Mr Andrews said significant changes had already been made after previous attacks, including changing bail laws and putting temporary bollards in the city. "I have been clear and from time to time I've been criticised for being very straight up and down, very straightforward when it comes to describing the very real threats that we face," he said.

Mr Andrews said he told Prime Minister Scott Morrison he had struck "the right balance" on Saturday when he called for Muslim leaders to take "special responsibility" for stamping out radicalism in their communities. "The statement from the board of Imams, the statement from the Somalian community yesterday, they are the ones I'd be guided by," the Premier said. The Premier said he was yet to speak with Mr Malaspina's family, but was hoping to do so. He steered away from speaking about the attacker. "There is work going on right now by incredibly brave members of Victoria Police and by doing that work they put themselves in harm's way in this very moment. I don't think (the attacker) deserves for us to be focused on him." Opposition leader Matthew Guy said he had been consistent in his messaging on crime.

"I'll bring in mandatory minimum jail time for repeat violent offenders," he said. "We don't tolerate and would never tolerate and accept that we should view, simply because our city is a now large one, that any violent extremism or problem with law and order is the norm. It's not the norm and we need to crack down on it hard," he said. He said he thought it was important to reinvest in deradicalisation programs and to ensure "our criminal justice system is the strongest it needs to be".
