+ International dialling access code. From a GSM phone, dial '+' to make an international call. From other phones a number code is used instead. This number varies according to the location you are dialling from and the telecommunications provider being used. Be aware that callers will commonly display the international access code for their own country when the appropriate dialling code to use is the one for the country from which the call is originating.

0010 AAPT 
0011 (voice) or 0015 (fax) Telstra
0019 Optus. 
0091 World Link
0096 Primus
