Well then, you'd also have to have an Australian Sims - they already have a boxing kangaroo as a team/mascot in Sims University and the athletic career in TS3 .. there is a llama but there is a roo too, pretty sure announcements in the newspaper of game scores mentioned a roo team once or twice.
The modern housing fashion in Australia has a lot of render, all different colours, usually a feature wall or portico, colourbond steel roofing, nobody uses wallpaper, houses that take up the whole block of land right up to the fenceline with hardly any backyard, maybe a courtyard and mass planting of the spiky plants such as cordyline, and since many of them don't leave much of a backyard, if they get a swimming pool it sometimes gets put in in the frontyard with a big wall around it. Ah yes the walls, retaining walls, planters, almost artwork driveways with assorted pavers and the letterbox made of a similar render to the house or pavers, part of the retaining wall or driveway. In the inner cities are the older style houses, federation or such. In the Eastern States most neighbourhoods have an RSL or a worker's club, with a bistro, live entertainment and lots of pokies, whereas in WA an RSL is actually for retired servicemen.
Surfing would have to be included, and surf lifesaving.
