Last month, the Supreme Court jury found three men guilty of planning to carry out a mass bombing attack on or around Christmas Day 2016 in Melbourne's CBD.

In November, Melbourne restaurateur Sisto Malaspina was killed and two others stabbed in the Bourke Street terror attack. Also last month, three men were arrested in terror raids, allegedly planning a deadly attack to kill as many people as possible.

Anti-terror squads are now factoring in risks of new technology such as drones, the assistant commissioner confirmed.

The Age understands Victoria Police's anti-terrorism department has concerns about the ability of drones to deliver or detonate explosives remotely.

The new-age security risks of rogue drones have been highlighted in recent days in London, where flights at Gatwick airport were grounded for nearly two days due to fears of unidentified drones flying near the runway.

"[Drones are] certainly a risk that, as Gatwick showed, is one that that's increasing," Assistant Commissioner Abbott said.

"There's a range of scenarios that we test and that's all part of our security assesment and risk assesment for any event".

In September, The Age revealed Victoria police's new three-year counter terrorism strategy that included deploying their own drones for surveillance over large-scale events. 

The Melbourne Cricket Ground will see up to 200,000 people enter its gates over the Boxing Day Test.

The Sidney Myer Music Bowl will host about 50,000 spectators on Christmas Eve for the annual Carols in the Domain, while tens of thousands of people will flock into the city and Southbank areas for New Year's Eve.

Melbourne Cricket Club's manager of venue and event services Gerard Griffin said the usual security measures such as security wands and bag checks would be used on every person entering the grounds.

"Security, safety, the wellbeing of patrons, it's uppermost in our minds for every event at the MCG," he said.

As per all events, Mr Griffin said items such as glass, lasers, fireworks and flares were prohibited, and punters were encouraged to use clear bags or no bags.

Cricket fans can expect an increase in plain-clothed and uniformed police throughout the venue.

Melbourne has been the target of 11 of the 25 executed and thwarted terror attacks in Australia since 2005, police have revealed.

The force has already taken steps to protect football and cricket fans at the MCG by banning most car parking outside games due to the risk of a bomb attack.
