Major General Stuart Smith confirmed the Australian Defence Force staged a G20 training exercise on Sunday night, but declined to comment further. Witnesses reported seeing at least 50 armed people dressed in camouflage during the operation from late on Sunday night to about 2am Monday.

We won't give all the details for operational reasons for all those rehearsals but the range of counter-terrorist, search and airspace safety surveillance will be practised. Major General Smith thanked the Brisbane public for putting up with what he described as " a bit more than normal noise levels." During the Eagle Street Pier exercise, it is understood Black Hawk helicopters dropped participants on to the training site and speed boats were also used. Brisbane television cameraman Eddie Norbido said none of the personnel wore any identifying clothing to indicate which agencies they were worked for. "They had the bad guys dressed up in proper clothing and arrested them at Eagle Street Pier and Waterfront Place," he said. They fired a number of blanks. It was quite authentic and a very professional show. The Queensland Police Service confirmed it did manage traffic in the surrounding streets for the operation, but was unable to say which agency had organised the exercise. A similar training exercise was staged last Tuesday at the Port of Brisbane, which included hundreds of ADF members. The G20 Leaders Summit will take place in Brisbane from November 14 to 16.
