Victorian bail laws are set to change after the Bourke Street Mall tragedy, in which a man allegedly drove through a crowd just days after being bailed on an assault charge.
The accused was bailed against the wishes of Victoria Police five days before Friday's attack.
Victorian Premier Daniel Andrews admitted he was frustrated with the bail system.
"It's my job, though, to take that frustration and that anger and the deep sadness that I feel, and that every Victorian feels, and to make sure that's put into reform and change," Mr Andrews told reporters on Sunday.

He foreshadowed changes to the bail system, in which Victoria uses volunteer bail judges for out-of-hours decisions.
"We do have a number of unique features of our system, but ... we have to have a close look at these arrangements," Mr Andrews said.
"If changes need to be made then they should be, and be in no doubt they will be."
Chief Commissioner Graham Ashton said he could not speak freely about bail, but it would be covered in a coronial review.
"We've expressed frustration over the course of the journey about bail issues. We haven't made a secret of that," he told reporters.
Opposition Leader Matthew Guy said the whole bail system needed reform.
"The bail system in this state is broken and it needs to be fundamentally reformed," Mr Guy told reporters.
He said Victoria would likely need to build new facilities to hold more people on remand if bail changes went ahead.
