I seem to recall some 20 years ago when digital delivery of software was still young, you would see things like buying Photoshop would cost 50% more if you were in Australia. I think it was because they were trying to keep in line with physical sales which were more expensive (probably because of somewhat reasonable reasons, like the smaller market, distance to ship, stronger consumer rights laws, sales tax, etc). These days it seems digital sales have taken over and regional prices aren’t as bad for Australia anymore.
