Marce, I can't remember how much you were involved in the closed (too hot to handle) "where to" thread, but most of this has been discussed, most fans have a view that isn't shifting and not all hold the same view.
From my POV the Super as implemented managed to cut support numbers down to the rusted-on, and then brought in the sand blaster to continue the trend. As things improve in a given franchise /union, the absent-rusted on return. For a bit. Even if not temporary it's not even a blip on the longer term trends. To return to strength requires the game to attract outside of the traditional rusted-on rugby fans to the general public. Fortunately in Australia it is a sports crazy market, and (at least compared to NZ) a sizeable market. We only need to attract 1-2% of NRL/AFL/Football fans to make a huge difference. If only we would get on with it.
Re-setting those game trends is where it starts. At the moment those trends are, a polemic difference in team quality between Aus and NZ, an absence of willingness to spread the available talent (including NZ players) across the comp (including Aus teams), hence a baked-in lop-sided balance in the comp, a predictable shortage of Aus representation in the finals, and a growing lack of interest in games between NZ teams. And a complete imbalance of funding to NZ v Aus teams. The NZ (and previous Rugby Australia) solution is shrink to greatness. Which does solve the quality and balance, without needing to adjust funding toward Aus - a logical solution if your only problem to address is levelling the playing field. It possibly builds strength in Qld and ACT. NSW would follow if they ever solve the impasse between NSWRU and SRU. And between SRU and the grass roots. Otherwise we have two solid franchises over time, and a possible third permanently dangling in front of the politics with brief flashes of strength.
But rugby here needs to broaden the imprint outside of traditional rugby background. That needs a domestic comp (like every successful code in Aus) with a domestic champion that gives the commentary Australian teams to focus on in the trip to finals. There is room after this for things like a TT or interface to Japan. IMO Rugby Australia needs to reset to a domestic comp, then ACT/Qld are powerhouses that need to self drive. Sort out the shit in NSW and leave them to self drive. Otherwise they need to focus on making Melbourne and Perth strong. And to look how to expand outside of that.
