Potential terrorists would be banned from Melbourne's CBD and satellite-tracked under a $89.5 million election promise by the Liberal-Nationals.
Opposition Leader Matthew Guy revealed his counter-terrorism policy on Wednesday, less than a week after Hassan Khalif Shire Ali set a gas bottle-laden ute on fire and went on a stabbing frenzy in Bourke Street, killing restaurateur Sisto Malaspina.
"I don't think we can have too much protection for Melburnians in the CBD and so we're going to give an even greater level of protection," Mr Guy told reporters.
Orders would be issued by a magistrate or children's court after an application from Victoria Police, with national intelligence agency ASIO able to make recommendations.
The order could include GPS tracking, living arrangements, exclusion zones, restrictions or prohibitions on communications, regular reporting to authorities and mandatory de-radicalisation and drug and alcohol programs.
The opposition also promised another 100 Victoria Police officers will undergo advanced counter-terrorism training. The force would also recruit 50 new surveillance and analyst staff and an additional 76 frontline officers to operate in street patrol teams.
Mr Guy, who cast an early vote on Wednesday, has campaigned hard on law and order in the lead up to the November 24 poll and accused Premier Daniel Andrews of raising a "white flag" to extremism based on his 2015 comments presenting it as part of contemporary Australia.
Mr Andrews on Wednesday dismissed the political attacks.
"There was no counter-terrorism command when I was sworn in as premier and it's now a very significant part of Victoria Police's work," Mr Andrews told reporters.
"We face very real threats and (we're) making sure that police have the resources, the recruits and the ... statute book that they need."
The first-term Labor government is also fending off threats on inner-city seats from the Greens.
According to the latest Herald Sun/YouGov Galaxy Poll, Labor would retain the marginal inner-city seat of Richmond.
Incumbent MP and Planning Minister Richard Wynne holds the seat by a slim 1.9 per cent and would attract 49 per cent of the primary vote, according to the poll published on Wednesday.
Greens support is at 42 per cent, with Mr Wynne ahead 54 to 46 on a two-party preferred basis, reducing the prospect of a hung parliament.
The Liberals aren't contesting Richmond.
The poll also showed former celebrity photographer Darryn Lyons, contesting Geelong as an independent, secured 15 per cent of the vote but remains behind Labor and the Liberals.
Greens leader Samantha Ratnam, campaigning in Richmond, was dismissive of the poll, saying seat-based polls had a "huge" margin of error and volunteers on the ground had been reporting significant support for her party.
The Greens have faced criticism this week for standing by their Footscray candidate Angus McAlpine, who once rapped about date rape and domestic violence.
Ms Ratnam is maintaining Mr McAlpine has been on a "process of change" in recent years but the revelations have further strained any hope of the Greens working with Labor as a coalition.
"I refuse to take that political party seriously," Mr Andrews told reporters on Wednesday.
