As a point of reference, it would take me at least 1 hour and 3 minutes to get to Brookvale via public transport, and I live in an area very well serviced by transport, especially to the northern beaches. For the sake of reliability, it was done on Google Maps, based on an "arrive by" option for any given Saturday at 3.15pm. If games are on at night, or on a Sunday, or even a week day, the transport options will be even limited, so I was being generous.
I really don't think, considering this, that I'll bother to go to a game up there, and I fear that that's the same decision a lot of people will come to ESPECIALLY those who don't have the luxury of A. A car or B. Good public transport options.
I understand the argument about it being a superior ground from a TV perspective - that makes sense - but isn't it the case that only one game per round will be broadcast (or am I making that up?). Why not appease the Manly/beaches by having games up their way when the Rays are drawn to get a game on TV, and then appease the north shore dwellers during rounds that aren't on TV?
Furthermore, there are other things that need to be considered. Healthy crowd numbers are just as important as healthy TV numbers - in fact most codes in Australia are somewhat superficiality judged by the former, not the latter. A brief glance at the 2007 ARC page on Wikipedia shows confirms this with the crowd figures for each and every game provided. Clearly it's the case that the ARU, or Australian rugby fans OR Australians in general judge sporting popularity/success by crowd numbers, so why try to diminish them by isolating an important stakeholder?
Anyway, I completely get the argument about it being rectangular, that's fair enough, but I feel as if this isn't a very intelligent compromise. It seems to me that the ARU are, typically, trying to do too much in one year. Look at the stadiums these teams are playing in - Leichardt oval, Brookvale, AAMI, NIB - these are all stadiums with a capacity well over what the teams will ever pull (except if the competition turns out to be amazing). They are trying to go for the glory image by playing in the same venues as NRL teams. It's clear that they're trying to send some sort of message, but in my opinion it will backfire as empty stadiums run balance books into the red.
