The difference is, in America skating is much bigger... More people watch, participate, pay! haha.. It is popular enough that they can receive MASSIVE amounts of sponsorship from big big companies... AT&T springs to mind, and I think a big jam company sponsored the last one?
Australia is a long way off before we get the "Coca Cola Australian National Championships"
The last one we got was Powerband in Melbourne, and they got a crackdown from the ACCC for fraudulent advertising and claims soon after... :S
(On the upside I got a free Powerband--- oh wait they ended up not working )
Fact is, until we are getting this kind of attention in Australia, we can't be expecting big money from ISA because they simply don't have it :S
