I knew I had an affinity for Australia for a reason. You can't make that up. Also, I had no idea that American Football (Gridiron) was as well represented in Australia. For me as an American, football is as natural as well --apple pie ---(another saying: As American as Apple Pie) but always thought it was probably strange to people from other countries ---it probably appears very mechanized, maybe militaristic with formations and gear --not fluid like soccer or maybe Australian Rules football. But anyway , take it easy, mate.
