Not at all on topic:
thor: Lace and Steel was a fantasy game set in a pseudo-Europe (not unlike 7th Sea), using Dumas-like musketeers and Grimm's fairy tales as major building blocks.
(It was probably one of the very first games to use relationships as modifiers to skill rolls. Also neat: When a sorcerer summoned a demon the player got to use all bad relationships to make the stats of the demon. The more hateful the summoner, the stronger the demon. This Aussie game was ahead of its time...)
Yes, anything based on Mad Max, i.e. most post-apoc, will be Aussie.
To my knowledge, there are no Kylie games. Nor are there AC/DC games.
The Matrix was filmed in Sydney, and there's lots of games inspired by that. Does that count?
