Do you know what a sellout is? It is where all tickets are sold, and there are none available for purchase.
The MCG used to attract 110k - 122k in the 60s/70s/80s as standing room was pretty much unlimited. Since they rebuilt in 1992, each GF has been a sell out and unless you are a MCC, AFL or competing club member, you cannot attend. The only time a competing team did not sell their allocation and the opposition members bought all of those tickets. Even if GWS made it, the Crows members would have bought any left over tickets (30K Crows members applied for tickets, 17500 were available). The fact that between 6 and 500 people with a ticket don't attend can be due to illness, travel or other factors. The MCC has 62,000 full members with entry privilege (and 300,000 other members), they leave some spots un sold for last minute walk ups on the day as this has been an MCC tradition for over 100 years. Whether the crowd is 99,500 or 100,018 depend of how many to those last sports are filled at the last minute. The average price paid by those that miss out on a ticket by legal means is over $1,000. My wife paid $1200 to see Collingwood in 2010. Tickets to the NRL GF can be bought all year for $50. I thought I was clever snapping up a NRL GF family pass in July for $180, but now that tickets are even cheaper/free this week, I will not be doing that again.
Most Melbournians dream of attending an AFL GF as it is nearly impossible to get tickets. That is one of the reasons why SOO sells well here and so would the NRL GF. We have an attendance culture.
If you insist on comparing Sydney to Melbourne and AFL to NRL, get your facts right.
ps. As a Victorian I know I will be bagged for talking about AFL, but every third post by a Sydneysider talks about AFL, and most it it is wrong.
Also, as passionate RL fans, I assume that all of you Sydney posters will be there on Sunday?
