CANBERRA, Aug. 5 (Xinhuanet) -- Details of the evacuation plan of the central business district of Sydney,  Australia's largest city, were released Friday with an SMS and e-mail alert system being the key measure in case of a terrorist attack.

    The plan, released by Morris Iemma, premier of the state of New South Wales of which Sydney is the capital city, is broadly modeled on the strategy used in the recent London bombings, Australian Broadcasting Corporation radio reported.

    The security alert system would see the managers of 1,500 building sites across the city receive an SMS message from an emergency command center.

    They would then have the job of directing people to three evacuation sites across the central business district.

    At those marshaling points, specially trained safety site marshals will provide information and direct people to the best transport routes home.

    "We have to be prepared. This is a plan put together with our experts ... it's based on learning lessons from other cities where attacks have occurred," Iemma told reporters.

    "It is about managing the risk and I hope that we are all wasting our time in doing this, but we have to be prepared," he said. Enditem
