You still need to fix the public transport problem. It doesn't matter how good or big the stadium is - if it means spending hours in traffic to get somewhere to then struggle getting a park or worse spending that time on a crowded bus, then many will still prefer to watch on TV.
What .... and put in place infrastructure that will see our private and pristine beaches over-run by great hordes of unwashed heathens and Parra supporters pouring out of rank public transport flinging kebab wrappers willy nilly every weekend ....... NOT bloody likely ..
It is not the intention of this post to identify or insult any specific kebab wrapper flinger ..
