I do wonder if having subbies clubs' reasonable costs all met by Dismal Pillock's offshore (Pitcairn) discretionary trust would help.
Everyone has been aware that it's getting harder to play organised sport on a weekend with the demands of the 'flexible' workplace etc, with player numbers fluctuating not just by the season, but by the week - especially if travel is involved.
The challenge seems to be as much about finding a divisional structure that can prevent situations like KOBs (and many other clubs). Perhaps the powers that be could considee combining two smaller clubs into a slot in a division (say, KOBS playes 1sts and 3rds, another club 2nds and 4ths). The trick is doing so without diluting the club atmosphere that makes Sydney Subbies such a great institution.
