this would only be if the nrl started from scratch, and it's probably a good thing they don't do that, because too much history and tradition would be poured down the drain. the only way to accomplish it without starting from scratch would be to relocate clubs from sydney and merge a couple who probably have every right and ability to stand alone in sydney, so i don't think it would ever happen now. for example: roosters would have to relocate to perth, bulldogs would have to relocate to adelaide, st george illawarra would have to merge with cronulla, bears would come back into the comp as the second brisbane club. actually i think new zealand should have 3 clubs because so many juniors are coming from there. so 18 teams, but keeping the top 8 finals:
north queensland - north queensland cowboys
brisbane 1 - brisbane broncos
brisbane 2 - south queensland bears
gold coast - gold coast titans
newcastle - newcastle knights
central coast/manly warringah/north sydney - "northern eagles" or "manly-central coast eagles"
central sydney - south sydney rabbitohs
cronulla sutherland/illawarra/south coast - st george illawarra sharks
parramatta - parramatta eels
penrith - penrith panthers
liverpool/macarthur - wests
canberra - canberra raiders
melbourne - melbourne storm
adelaide - adelaide bulldogs
perth - perth roosters
auckland - auckland warriors
wellington - wellington ???
christchurch - christchurch ???
