Special powers have been granted to Victorian police under terrorism legislation ahead of Israeli President Isaac Herzog's state visit.
The powers will allow officers to stop and search vehicles or people in a public place and ask for identification in specific areas where Mr Herzog will attend while in Melbourne.
Thousands of demonstrators are expected to pack city streets on Thursday afternoon in opposition to the Israeli president's arrival.
The new powers are not designed to impact the protest, police said.
Victoria Police Deputy Commissioner Bob Hill told reporters there was no intelligence suggesting a specific threat, adding the powers were a preventative measure.
"However, we are well prepared for both the visit and any protest activity this week, and have adequate police resources available to provide an agile response to any incidents," he said.
It's hoped the protest will remain peaceful after demonstrations turned violent in Sydney earlier this week.
At least nine people were charged, and 27 arrested after protesters were punched and pushed by police during an anti-Herzog rally in Sydney's CBD on Monday.
Mr Herzog will fly to Melbourne on Thursday morning, with police confident the significant operation will ensure a safe visit.
"Those powers will be invoked tomorrow and it relates to those areas that the Israeli president will be visiting," Mr Hill said.
The powers have only been used a handful of times since 2006, including the Association of South-East Asian Nations (ASEAN)-Australia Special Summit and the Land Forces expo.
"We understand that this visit has caused some emotions to rise in some community groups. We're conscious of that," Mr Hill said.
"We're also conscious of the security arrangements that we are required to deliver to ensure this visit is delivered in the most safest way."
