I don't think it will happen. The Aboriginal Australians have a taboo against depicting the dead. Plus the Aboriginal Australians, like the Inuit, were among the most technologically primitive culture groups on the planet. I'd love to see a game about hunter-gatherers, but I don't think Civilization is really set up to accurately portray that kind of lifestyle.
Reminds me of the debate about Huns inclusion Civilization V- lots of people were saying when you already have non-playable 'barbarians' in the game, it doesn't make sense to have a 'civilization' in the game that would usually be characterised as such. But then I don't see anything wrong with there essentially being a 'play the barbarian option', and Attilla's AI was correctly set up to inevitably declare war on everyone at some point.
