No it's does not disprove any point. Newcastle happens to be NSWsure 2nd largest city. Just like rugby league test are given to Old Trafford Manchester instead of London. Both Newcastle and Manchester are major cIties and are well and truelly fine to hosteoporosis such test matches. The bottom line being that the ARL have erred in stating the Kangaroos v LIONS would not be feasible. Proactive and decent sports marketing suggests that such a test match would be a win/win both crowd and tv ratings wise. But this is not to be! The mistake has been made!
Yes it is NSW's second largest city but I don't know why you compare it to Manchester. Greater Manchester has a population of 2.5 million and two of the largest and most iconic football clubs and stadia in the world, Newcastle is awesome but it is a regional centre with a population of 0.5 million - you are not comparing apples with apples.
If it truly were the much sough-after event that you claim why would it not be played at ANZ like the pinnacle in other rectangular sports is when visiting NSW?
Also, on feasability of the test are you privy to the financial estimates prepared by the NRL of what a one-off test match played against GB would cost vs earn? To make these claims I assume you have access to these documents. Could you please share them?
