Well excuse me for being totally bored with the discussion when the way it's gone is I say something, you say it's impossible, I say it's worked for other people so obviously it is possible, and you ignore that and just reassert that it's impossible because you made up some numbers and your mates said so.
It's lame argumentation made by a person who refuses to be open minded to possibilities that they hadn't considered.
You say most stadiums in Australia aren't profitable, so what!?
Any business that is poorly setup and/or poorly run is likely to fail. Most restaurants fail for example, but that doesn't mean that restaurants can't be successful businesses.
Anybody with a brain can see that 99% of the stadiums in Australia either don't have enough tenants to be sustainable, aren't built to fit the needs of the market, are built in a bad location, or some mix of the three. Don't make those mistakes and live within your means and you could build a sustainable stadium business in Australia/NZ just like Docklands, the MCG, and stadiums all over the world have managed to do.
But again the value in the NRL owning a stadium would be in owning the land as an asset, not so much in the stadium it's self.
