Let’s get one thing straight here: no matter what happens, the sports business in Australia will never be the same as the sports business in the US. It’s just not going to happen.
Now I know that some people like to talk about the Americanisation of sport in Australia and yes, there are things Australian sporting codes are adopting because they have worked so well in the US such as salary caps, the reverse order draft, and free agency. The primary reason for this is because the leagues want to make a better game. Better games mean more fans and more fans mean more money. EVERYTHING is [nearly] ALWAYS about money. But is it working well? Eh. Not in my opinion.
