This is a bit reductionist. There are plenty of countries around the world where "football" doesn't refer to soccer (i.e. any country with a large national football code, gridiron, or rugby)... Australia, new Zealand, South Africa, Pacific islands, Ireland, etc...
Football simply means Aussie Rules in Australia. Don't lump us in with the yanks lol.
Cannot believe this is controversial tbh, I hate creeping Americanisms as much as the next guy, but the very fact people are arguing about it here is proof that "football" is ambiguous in online spaces
