I have to disagree a bit there.The end of the AFL/NRL season had basically no effect on the attendances of the clubs
You may be correct about other clubs I have not looked at the numbers, but as far as our club is concerned...
Average attendance
During afl season : 9683
After afl season (excluding AO games) : 10783
After afl season (including AO games) : 12232
Total : 11552
