Police tactical units, paramedics and firefighters have been among those taking part in the drills.

The operations are being run in collaboration with Gold Coast City Council and the Department of Transport and Main Roads.

As reported by ABC News, the drills are designed to prepare the city's services for a "worst case scenario", with their reaction times also tested.

"We are picking something that would be the worst possible thing that could happen during the Games," Queensland Police Deputy Commissioner Steve Gollschewski told ABC News.

"You can look around the world and see the sorts of things that happen that really, really confront communities and that is the sort of thing we are talking about."

The drills are the latest action being taken by local authorities to ensure the safety of the Games.

In December, Queensland Police launched "Operation Sentinel Unite", a three-part safety awareness programme set to aid the Queensland Police Service's crime prevention responses in detecting, deterring and disrupting criminal and terrorist activity.

The project also included behaviour observation and suspicious activity recognition training for police, which was launched earlier last year.

It is hoped the initiative will provide the public with information in the event of a critical incident, particularly in crowded areas.

A mobile forensic facility and response motorbikes will be utilised for management of counter terrorism and major crime investigations.

A total of 3,500 police officers from Queensland and 4,200 security personnel will be present at the Games, along with 2,000 members of the Australian Defence Force and 100 officers from the Australian Federal Police.

It means a security force of more than 10,000 will work together to ensure the safety of athletes, officials and spectators.

The Gold Coast 2018 Commonwealth Games will take place from April 4 to 15.
