AFANA updated things last week.
Aussie Rules will be on Fox Soccer Plus in 2012, and 2013-14, assuming FSP sticks around that long. Typical coverage promised will be 2 live games per week, plus an hour long highlights show (which we haven't had in the US in probably 10 years or more!) So, if you have FSP for Rugby from Australia or for other reasons, you're in luck.
For me, after all the recent price rises, I'm not sure I want to add another $15 to my monthly bill. As FSP is a part-time HD channel, its not clear whether the Aussie Rules will be coming in HD or not. (Apparently not all games are broadcast in HD in Australia yet!)
