The only way to ensure fairness is for every club to play each other once, or (preferably) twice. End of story.
As the league expands this will only be possible by dividing the competition. I think this should not be a partition based on results (promotion/relegation) but on chance, so that each group is re-randomised each year. That comp could enlarge to 24 clubs, two, 12 club groups.
Downside, of course, is that certain blockbusters might not be played in a particular year. (E.g. if Carlton & Collingwood are not in the same group they either won't play each other until the finals, if at all.)
I suppose the alternative might be a 24 team comp (current 18+NT+Tas+Canberra+N.Qld+another W.A./Perth+another S.A./Adelaide) where everyone plays each other ONCE, 23 rounds.
