It's correct except for SA's borders and the flag is roughly 50 years too early. Their borders for WA are wrong.WA was already established by 1836, and SA should be too, or within the year by event.
But at least they're there unlike Vicky2. One thing I did like though is Victoria can get annoyed with NSW and opt to either split them or gift them to one of the other states which is sort of accurate, its why NT was given to SA historically.
