What is the cheapest way to call Australian landlines?

[k_au_12344]

Hi
I've just arrived in Singapore and am looking for the best way to call Australian landlines and mobiles.
I have an unlocked mobile phone that can access internet, cable broadband internet (not wireless), a work computer locked from using skype, and a fixed address for the next 3 months.
I'd be interested in hearing about options trialled by Aussies here in Singapore and seeing what you have found to be the best/cheapest.
Thanks heaps
K

Try calling cards. Not sure which is cheaper but either Singtel or Starhub to my knowledge is cheap as.

Try using the Chatchat calling card by the Shinetown company. They have good rates to other countries. If you're using a SIM card which allows free incoming calls, then you dial the callback number of Chatchat and their system calls you back and then you follow the voice prompt to make your overseas calls. Later on, you can also top-up the value via credit card.

Hope this helps.
