Bloody expensive to service as thy require a special transmission oil specifically engineered for Nissan for that particular CVT.
I have heard ~$1300 for a trans service (correct me if I am wrong guys).
Also, if it breaks, good luck finding someone in Australia to fix it.
They are truly a fantastic transmission though.... smooth as silk.
As Zei said, definitely do a search BEFORE making a decision so you have more of an idea of the positive's and negative's
