First Post so be gentle.
Just found this special from OZgameshop email. To me, AU$30 sounds like a cheap price for an official XBOX wireless controller.
Personally I bought two PS3 controller from them. And they feel like official ones. Delivery time was not that bad, recieved in 2 weeks after purchase.
NOTE: It says "Items is brand new and official but does not come in retail packaging, split from console bundle"
So If that matters to you, you may like:

Which comes with Official package but 5 dollars more.
Not as cheap as the previous deal but still a very good deal since it's probably not an error in price!
