Serous Siv. You honestly think those clubs are growing. Poor old Newtown and the Bears are nth anywhere near the top flight status. The others you mention are not known by the mainstream public . It's top.flight status or zero as far as notable growth for any club . That's the way it is in Australia. Sure you can get your boutique speciality clubs with beer festivals etc but they are not mainstream discourse/knowledge.
If you compare them today to 2005 there has been growth. Small but steady growth
7000 turning up to a Jets games is evidence of steady growth
