Hello, I must provide you detail calling guide(for tourist) info as per your template from Australia to other cities and vice versa (to landline and mobile) because I am very much familiar with international phone dialling system and rates..Here are some basic info, please read this:
The international country code for Australia is 61 and phone numbers within Australia usually have 10 digits - 2 for the area code and 8 for the number. A typical Sydney number might be listed as (02) 9876 5432. If you were calling this number from outside Australia, you would add your international dialing code (usually 00), add 61, drop the 0, then the number. So calling the example number would be 00 61 2 9876 5432.
The area codes for the main Australian cities are:
Adelaide - 08
Brisbane - 07
Canberra - 02
Darwin - 08
Hobart - 03
Melbourne - 03
Perth - 08
Sydney - 02
