I hate the way they (like many businesses now) treat us like idiots. The secrecy about member numbers and seat allocations is to give themselves licence to do what they want.What they need to release is the breakdown of Full/Silver club support for each club. They used to do this but stopped about 10 years ago. What happens if say Collingwood has 10k Full Members and Essendon has 8k full members and they meet in a GF, will they all be guaranteed a GF ticket?
Another thread has the member numbers from the last time they were published, in the 2014 annual report. Ignoring those who didn't nominate a club of support, Collingwood had 25.1% of members, Carl next at 14.5%, Essendon 12.9%.
This includes silver and absentee. So very rough, but if Coll and Carl played in a GF and percentages for Gold were similar, that's just under 12000 seats. No reason why they shouldn't be able to get tickets, but who knows with the AFL.
