Residents of Australia's largest city are being urged to create survival bags to prepare for terrorist attacks and other emergencies under a campaign launched by city council Tuesday. The so-called "Go Bags," featured in a new terrorism awareness campaign by Sydney's city council, would include maps, a radio, a first aid kit, an extra set of keys, some spare change and important documents. The campaign urges Sydney residents to consider how they would make contact with friends and relatives during a terrorist attack or other emergency, when mobile phone services are often disrupted. The council's acting chief executive, Garry Harding, said Sydney residents need to prepare for a serious incident like a terror attack. "You can't ignore what's happened overseas, you know we're all aware of that," Harding told the Australian Broadcasting Corp.
