Best Phone Plan/Prepaid for International Calls to Sri Lanka

Hi All,

Ever since Belong got rid of it's free international calls to Sri Lanka - it's difficult to find a plan/prepaid plan that allows for this?

Are there any options - with even a high amount of minutes per month? Vodafone seem to have 100 minutes per month. Telstra's plans are naturally quite expensive for the unlimited calls.

Any else using something better?
