You're right a city the size of Melbourne in a country like Australia that has 4 major winter football codes should have at least 2 quality rectangle stadiums to accommodate the 3 football codes that have varying needs all year round. They have built the small one(30K) which begrudgingly suited the common enemy of the 3 codes and it seems they have no intention of ever building the larger(50K) one that threatens the paranoid mongrels the most.
So the 3 rectangular codes need to stop ignoring each other and unite with one formidable voice to defeat the persistent attacks and stifling tactics of the 1 selfish dick that has plagued this country's sporting landscape for way to freakin long.
It isn't that difficult is it? They just need to be persistent, loud and smart from a marketing point of view. Lobby and recruit the media to help out. Good press is what it is all about. Pollies only do things that make them look good. If the press and public get behind it then it will happen and the only way that will ever happen is if we can get the press on our side, then the public will be swayed and then the pollies will build.
Three codes should surely have enough influence and pull in the media that can get them on board, then the rest of the dominos will quickly fall into place. It's all about perception.
