A two division system won't work...its not part of Australian culture. Eg A-League is created on Australian culture, Division system is not something we have done and it devalues the State comps in Perth and Adelaide. Plus the costs would outweigh the revenue...
Actually, the VFA up until #1990 had a 2 division league with promotion/relagation, and the Ammos (VAFA/amatuer league) in Melbourne has more divisions than I can count. That said, it won't work at a fully professional (ie AFL) level, for the reasons already given above - a 2nd division comp would not be viable and the gulf between it and the 1st division soon become too great to bridge.
A second tier comp (maybe East Coast) could be possible at some time in the future (costs too much ATM) - but only as a second tier comp, with no promotion/relegation to the AFL.
Its more likely to work for soccer then it is for football - Aussie Rules.
I am simply obeying FFA protocol re calling soccer football
Ya, I don't agree with the stance... And if we want to be technically correct, you should call AFL - Australian Rules, AFL is only the name of the league.
The FFA want Association Football (soccer) to be only called simply 'football' - nothing else - like they own the whole sport.
Likewise, the AFL (Australian Football League) market not only their own competition, but also the actual code itself as 'AFL' in the northern states (hence I forgive macadamia for the misuse of 'AFL' - I blame the AFL).
Both these football competition outfits are doing this for cynical corporate branding reasons, and both are equally wrong. All the more reason to resist what they tell you to do and say.
