Security at the Boxing Day Ashes test in Melbourne will be beefed up after a car ploughed into pedestrians in the city this week.
Police said officers will be “highly visible” both inside and outside the cricket ground for the fourth test between England and Australia the day after Christmas.
Widespread bag searches will also be taking place.
A dozen people are still in hospital after 19 pedestrians were injured when an SUV driven by 32-year-old Saeed Noori, ploughed into Christmas shoppers outside Flinders Street station on Thursday.
Victoria Police’s assistant commissioner Stephen Leane said: “Our presence won’t disappear when play is finished.
“Whether you are heading home or into the city, fans will see police right across Melbourne.”
Transport hubs, popular tourist spots, such as Federation Square, and routes to the Melbourne Cricket Ground will see increased patrols.
Victoria premier Daniel Andrews urged people to remain vigilant.
He said: “Victoria Police have the resources and have the resolve to do everything that needs to be done to keep the community safe.
“If it takes a bit longer to get your bag searched, that’s being done for your safety and I would ask that you are patient, that you are as cooperative as you possibly can be and that you remain vigilant.
“If you see something that you don’t think is right, speak to one of the many members of Victoria Police that will be out and about over this really busy period.”
Noori, an Australian citizen of Afghan heritage, was charged with 18 counts of attempted murder on Saturday.
Australian Prime Minister Malcolm Turnbull said police have not identified any terrorism link to Noori, but added nothing should be ruled out.
The suspect has a history of mental illness and drug abuse, police said.
Mr Turnbull added: “This was a despicable and cowardly act.
“But I want to reassure Australians that this is an isolated incident.
“We should continue to go about our daily lives the way we always do.”
England will take on Australia in the fourth out of five Ashes tests after a disappointing first three matches in which the team lost the urn.
