Calling Australian mobiles from nz

[daicoses]

Hello, just wondering if anyone knew of a cheap way to call aussie mobiles from nz. Calling from skype is AUD 26.4 cents/min, and the best calling card i can seem to find is talk'n'save for about NZD 21.3 cents/min. Some cards are a bit cheaper but don't have queenstown access numbers. Talkster doesn't do nz yet. Any ideas?
