There would be VAFA clubs open to hosting finals. Not hard to keep the reserves at 11.40 and seniors afterwards. They are fixated on making finals as inconvenient as possible.
There may be, unfortunately a lot of clubs can't host. Councils often don't allow outside or non council boundary based teams to play on grounds when the host teams season has concluded.
As most clubs have finished for the year, councils like getting the grounds prepared as early as possible for the upcoming summer tenant (Oct 1).
