it won't happen because Albo wants it asap, but PNG should be team 20 and come into the league in 4-5 years time. announce it now for all I care, but get into the high schools now and build a proper schoolboys tournament, ensure for elite pathways and coaching, and have dev squads, 16s, 18s and 20s sides to play in the QLD junior rep comps and then bring them in when it is time.
with the eyewatering amount of investment going into the side they won't have any issues with success down the track, but they are going to be anchored to the bottom of the ladder for at least 3-4 years if they get brought in for 2026, hypothetically.
as for teams 19 and 20, they have to be Perth and NZ2 (South Island). SA, Tassie and the NT is AFL central, leave them be, but the interest in league in the West has always been strong and we need a second NZ side to tap into the Union systems even further.
then we can talk conferences.
