^ It is not supposed to work and the Australian Communications and Media Authority explicitly advises that 911 is not an emergency number in Australia. It was at one point an actual area code in parts of Australia, which was reportedly one of the reasons why it was not chosen as the emergency number.
Some mobile handsets are programmed to recognise 911 (and sometimes also 999) as an emergency number, and will automatically redirect these to 000. This is done by the phone itself, though, and it sends the call out as an emergency call. The actual number 911 does not work as an emergency number in Australia.
