Will never happen but the only way to have a truly national competition that makes long term sense (despite short-term pain) is to split Sydney into 6 regions and have one team per region.
Sydney City - merge Roosters and Rabbitohs
Sydney North - merge Manly with the old Balmain Junior area
Southern Sydney Sharks - merge St George and Cronulla
Western Sydney Panthers
Parramatta - biased I know but we remain simply on the back of the growth of CBD and the fact we are already the only true second city in metropolitan Sydney (with our stadium).
South West Sydney - merge Canterbury and the Western Suburbs part of West Tigers
With 3 spots available, add Central Coast, 2nd Brisbane team and a Perth team.
Personally, I would lose NZ to add another team based in Adelaide.
So, Canberra, Newcastle, Melbourne, Adelaide (or NZ), Perth, Gold Coast, Central Coast and Nth Qld each with their own teams. Brisbane has 2 teams. Sydney has 6 teams.
Split these into 2 conferences with 8 teams each: A and B.
Conference A: Brisbane 1, Brisbane 2, Nth Qld, Gold Coast, Perth, Newcastle, Central Coast, Sydney North
Conference B: the 5 remaining Sydney Teams and Melbourne, Canberra and Adelaide (or NZ)
Play each team in your conference twice = 14 games
Play each team on other conference once = 8 games
Conferences play off their top 4 in a pool style against each other once to get top 2 - so 3 weeks to determine top 2.
Top 2 from each conference play off in a
A1 v B2
B1 v A2
Winners progress to National final.
