Loudspeakers (top-R) are attached to traffic lights on an intersection in central Sydney, Australia's biggest city, 01 August 2007. Australian authorities revealed new anti-terror measures 01 August, ranging from loudspeakers on city streets to plans to secretly search and bug homes and businesses. Dozens of speakers have been installed around Sydney's central business district to tell people what to do in the event of a major emergency like a terror attack, the state government said.

The complete system is due to be in operation ahead of the summit meeting of the Asia-Pacific Economic Cooperation (APEC) forum in Sydney next month, which will draw 21 leaders including the US President George W. Bush. The installation of loudspeakers on the streets of Sydney, meanwhile, was greeted more lightly by the media as a sign of the sort of citizen control employed in countries like North Korea.

澳洲最大城雪梨八月一日在市中心十字路口的交通號誌上架設擴音器（右上角）。澳洲當局一日宣布新的反恐措施，包括在都會街道上加裝擴音器，到計畫對一般住家和商店進行祕密偵搜和竊聽不等。省政府說，雪梨市中心商業區就架設了數十具擴音器，一旦發生恐怖攻擊等重大緊急事故，可以立刻告知民眾。

這整套系統預定下月在雪梨召開亞太經濟合作會議高峰會前就可以開始運作，亞太經合會將有21國領袖與會，包括美國總統布希在內。但在雪梨街道架設擴音器，被媒體插諢打科說，這是北韓等國家才會使用的控制市民伎倆。
