In the USA it's 911, in the UK it's 999 - what is it in Australia?
Triple Zero (000) is the primary national emergency number in Australia. The Emergency Call Service is operated by Telstra as a condition of its telecommunications licence, and is intended only for use in life-threatening or time-critical emergencies.
Prior to 1969, Australia did not have a national number for emergency services; the police, fire and ambulance services possessed many phone numbers, one for each local unit. In 1961, the office of the Postmaster General (PMG) introduced the Triple Zero (000) number in major population centres and near the end of the 1980s extended its coverage to nationwide.
