First past the post does not appear to have a negative impact on the EPL, or any of the other (major) association football leagues around the world. Having it here might be just as successful, although it could take a while for the fans to get used to it.
My only concern is that it would be extremely difficult to implement a workable elimination style tournament along the lines of the FA or Carling Cup in the UK. Imagine having a team like Manly, for example, playing a NSW Cup side, it should be obscenely one-sided. It becomes even more complex when you consider the feeder-side nature of Australian clubs. In this context, maybe an end of season Origin competiton/tournament would be an appropriate replacement?
