About 800 police from the US and NZ will arrive in Brisbane in three weeks to train for security detail during November’s G20 leaders’ summit.

Queensland will become a police state in November when around 6000 Australian and foreign officers join forces to provide security during the G20 leaders’ summit.

Around 800 police from the United States and New Zealand will arrive in Brisbane in three weeks to undergo intensive training for their roles in protecting visiting dignitaries and the Queensland community.

Some 600 Australian Federal Police officers have also been recruited to join their state counterparts to form a massive security presence during the G20, which gets underway on November 15.

During a visit to Brisbane for a G20 training exercise on Monday, federal Justice Minister Michael Keenan said he was confident the police will be prepared for any emergency or threat.

“The safety of the community is the highest priority of government and we are well developed and well rehearsed in our national security arrangements that will be in place here in Brisbane for the G20,” he said.

Around 800 participants took part in Monday’s training exercise to perfect the process of getting world leaders off planes and into the motorcades that would take them to their hotels.

The federal government has bought and leased 25 special protected vehicles for this purpose, however Mr Keenan has refused to reveal the cost to taxpayers.

He said the exercise, which involved role playing, was not designed to address a specific threat against any leader.
