On December 31st, I reported Google short-changed Australian publishers due to a currency conversion issue. After about ten days, it seems like these Australian and New Zealand publishers were now reimbursed for the difference.

I've gotten word that publishers affected by this issue have received any payments due, so I'm going to go ahead and unpin this thread.
Please feel free to post or contact AdSense support if you have any further issues related to this.
Thanks everyone, Jordan
What happened was, Google inverted the currency exchange rate between US and AUS. So instead of getting the 114% rate difference, they got the 88% a rate - a big difference.
