Or were you meaning something else?![]()

But yeah, an Australia civ could be interesting, but I don't think it will happen since we already have the Polynesians. Yes, I know they aren't the same, but an Australia civ would likely be a modern version without the Aboriginies. Why? Because IMHO, the Australians first became globally important in WWI. Now I might be wrong, but what possible Leader/UA/UB/UU could they have from before then except for an Aboriginie warrior UU? If they are added, they'll probably be one of the last civs made specifically for Civ5.
That being said, I would definitely DL a player-made version of them if it was fairly high quality?
