And what is your point? How does the number of people turning up to another game show anything with regards to the success of the A-league?
My point is that Australia looks really bad in rugby as we play NZ and NZ teams about 30 times a year. No one cares that the teams in the A-League would get slaughtered in Europe.
No one cares in the US that the US College Football teams would get slaughtered in the NLR but they still get over 40k attendance
The NRL and the AFL get away easy as no one else really plays the game.
People will watch the A-League because it's on at a convenient time, and they can actually attend the matches. As many people stay up at unsociable hours to watch the Premier League, and even more so the UEFA Champions league, because they are of a much higher quality than the A-League. I don't know how you can fail to see the significance of a touring side like Arsenal drawing a bigger crowd than the biggest A-League game of the year.
In bringing up the NRL and AFL, you've totally ignored their hsitories. Both used to have different names: The NSWRL and the VFL. They weren't the only Rugby and Football leagues in Australia, but they eventually dominated the WAFL, SANFL, and BRL. People in Brisbane, Perth, and Adelaide were more interested in watching the Sydney/Melbourne competitions on television. Very quickly, the West Coast Eagles, Adelaide Crows, and Brisbane Broncos drew bigger crowds to their matches than the entire local league on a weekend. People felt those leagues were of a much higher standard, and made the switch.
Australia looks really bad in rugby because our teams are under-performing. Badly. At the same time, Super Rugby audiences have taken a dive in Australia. This is because the quality of the games have been low. There is no point promoting derby matches when they're of minimal bearing as to who will win the competition; they've lost their meaning.
The quality of professional rugby in Australia will drop more markedly if we decide to leave Super Rugby.
Something needs to be done to make Super Rugby viable again, I do not question that, but it comes down to more meaningful games and more competitive teams - i.e. improving the quality.
