Here's a quick link in the news. It was Australia after all.

I do not fully understand if the reason for banning was that scene in particular (which is completely illogical and arbitrary) or because the whole game is extremely violent (which makes sense). I can understand the second point of view if you are banning violent games, but making a decision on one fake (within the game's fiction) rape scene while disregarding everything else would indeed be weird. Maybe it was just the press shifting the issue the way they like to do.
