Victoria Police has undertaken extensive preparations to ensure the safety of people attending Thursday's Anzac Day events and ceremonies.
Divisional Commander Acting Superintendent Craig Peel said police would maintain a strong presence at the Shrine of Remembrance and throughout the CBD as part of Anzac Day services and ceremonies.
"No matter where you are paying tribute or how you are spending your Anzac Day, know that day and night there will be a strong and dedicated police presence," A/Superintendent Peel said.
"Police have undertaken extensive preparations for Anzac Day events and ceremonies to ensure it is safe for everyone attending."
A wide variety of units will be in attendance, including general duties police, transit police, operational response units, highway patrol units and Protective Services Officers.
Extensive traffic management systems will be in place to ensure the safety of large crowds travelling on foot and public transport.
"We're expecting tens of thousands of people to attend the dawn service in Melbourne and significant road closures will be enforced."
A/Superintendent Peel said police will also have a strong presence in and around the MCG for the two big clashes taking place tonight and tomorrow.
"For those heading to the MCG for the Anzac Day eve or the traditional Anzac Day clash, know that we will be there in high numbers to keep you safe.
"Let us be clear - police will not tolerate any behaviour that compromises the safety of others.
"We want people to come out and enjoy the events and ceremonies, so our focus will be on ensuring everyone arrives and gets home safely."
