The International Award Payment Center Attempted Fraud by obtaining monies upon promises of Cash Award payment. Kansas City, Montana

Similarly to other reports on this site, I have received correspondence from The International Awards Center in Kansas City, MO. This arrived by Express Courier bearing a Priority Mail, Postage Paid tag with the words "LEE'S SUMMIT, MO. Permit No. 5696"
As I live in Sydney, Australia(and have no connections with this organisation)I was curious as to what sort of scam this might be.
Promises of a AUS$15,000 award(if I would agree to send $25 to the Sender by return mail).
Needless to say, I was not prepared to take this at face value and so I proceeded to do a search on the internet(where I found numerous reports of identical letters being received by other persons both in Australia and other Countries).
This group of scammers needs to be tracked down and placed before the US Courts(where they can get appropriately rewarded for their efforts). BEWARE!
