Revellers have been warned to behave and not spoil New Year's Eve celebrations in Melbourne for others as the countdown to 2018 begins.
Police will flood the city centre and party hot-spots to stamp out any drunk and disorderly behaviour, Victoria Police says.
"We want to see everyone enjoy themselves but to also reflect on their own behaviour and the actions of those close to them," Assistant Commissioner Andrew Crisp said on Friday.
An estimated half a million people are expected to flood into Melbourne to ring in the new year but police say they don't want people to behave inappropriately.
"It is why we're focusing on anti-social behaviour, violence, and drink and drug driving," Mr Crisp said.
Specialist squads including Water Police, Mounted Branch, Public Order would be deployed if needed, the assistant commissioner said.
Extra trains, trams and regional services will run in order to get revellers home safe, a Public Transport Minister spokeswoman said.
"We're putting on 541 extra train services to and from the city on New Year's Eve on top of the normal Sunday service - which is 100 more services than last year," the spokeswoman said.
However because New Years Eve falls on a Sunday, Night Network bus services will not operate, she said.
