Is it possible to get Bing Rewards in Australia?

Hi,

Bing gives rewards for using them in the US.. http://www.bing.com/explore/rewards

The rewards actually seem pretty decent, people in the below xda thread are talking about a $20 amazon gift card per month.

This is something that interests me greatly, is it possible to do it here?

Thanks
