Silent Hill f's has not actually been banned in Australia.
The Australian ratings board has been known to refuse to rate games fairly regularly, with the likes of South Park: The Stick of Truth and Wasteland 3 having to be edited to release in the country. While it has calmed down in recent years with the introduction of the R18+ rating in 2013, some games like Sludge Life and Hotline Miami 2 are still unavailable in Australia. It looked like Silent Hill f would be the next game to join the list, but it seems like that was a mistake.
