Your hatred of the AFL is blinding you.
Sigh.
Since the gabba upgrade, the QLD government have completely rebuild Lang Park, and Build the GC titans home ground. All without any funding from the NRL, Soccer or Rugby. Not to mention whatever they put into Dairy Farmers stadium up in Townsville.
So what? None of that makes it any more sensible to fork out more money for an AFL venue. If anything, the fact that they have spent so much money on stadia already makes it even less sensible to spend more now.
That seems a disproportionate allocations of resources against AFL and cricket.
Hmmm funny that. Which winter sport is more popular in QLD, again?
The QLD government have also received a $5b windfall from the minning boom.
I'd suggest that they might be looking to spend some of their mining windfall (however much it is) on things such as health, education, police etc.
