IMO it's just too early for them. They should be aiming for the tv deal after this upcoming one if they want a chance (so, around 2020). The population just isn't there, there's no stadium (the government will only build it if they get the license, not before. However the NRL only wants bids that already have a stadium) and it won't add much value to the comp. Not to mention that there's a chance it could destabilise North QLD.
Sure they might bring in big $$ from the mining companies but I'd much prefer they got behind the Cowboys and made them stronger.
It's awesome that they have really passionate people behind the bid but I'd much prefer the inevitable fourth QLD team to be in SEQ/Brisbane.
