You obviously havent been to any NRL teams licensed clubs in Sydney/NSW or spent any real time there. They are inextricably linked to the football club because usually down the road is a competing RSL club
Never said you did. Its the only ground I questioned you on and agreed with your other criteria.
Once again you dont have the experience of these clubs. Most clubs charge a nominal $5-$10 and 98%+ dont turn up to the AGM or vote in the elections. The clubs in their constitutions usually have clauses about supporting the football club and junior development and other community sports.
I am aware of all of that, but some of these clubs are massive. They generate tens of millions a year and are based in buildings worth similar amounts. A couple of million a year in grants is chicken feed when they're spending many times that on new and improved facilities.
If these places have such strong links then you'd think more than a handful of them would show up to games. The football teams are actually going the other way, moving away from their traditional homes (in some cases where the pokie palaces are) to play at grounds like ANZ and the SFS.
