Saving on my phone bills

I just bought the subscription for unlimited Australian phone calls in Skype(Only cost 3.95 Euro per month). Because I have lived in Sydney for a year, so I have some friends in Sydney. And I lived in Brisbane now. That is the reason I made a lot of interstates call. By using unlimited australian subscription from Skype, I can call every interstates free(but landlines only!). Moreover, I have a NSW phone which is linked to my Skype. As a result, my friends in NSW can call me as a local call.

One extra things, my current phone plan at my home is not free for local call, that is 20 cents per call. I even can save the money for that too!
