Of course there's then the Waratahs fans who have liked Super Rugby but might not be engaged with club rugby.
That is a very interesting point and well worth exploring, because I would suggest that there are many Super Rugby fans who have no tribal/locked on local club (Shute/Dewar/Premier/Pindan, etc) affiliation.
When I spent time in Perth, I got involved with Joondalup, because my son played for them, so lots of junior rugby, but I rarely watched any of the top level senior club rugby.
In Melbourne, I will occasionally go watch a Dewar game, but I don't really follow any particular team.
For me, my rugby affiliation and day to day support (time and money) is Melbourne Rising (NRC), Melbourne Rebels (Super Rugby) and the Wallabies (National).
I wonder if, teams aside, that level of engagement matches the experience of anyone else on these boards.
