If PVL wants 5 teams in Queensland, which is the correct number, then 4th and 5th will be based in SEQ as that's where the population is based.
Sunshine Coast isn't ready for one, so its best hope is to team up with Redcliffe and play a couple of games a year at Sunshine Coast Stadium once it has its capacity upgraded. That leaves Ipswich/SW Brisbane and Logan/SE Brisbane to battle it out for the other spot.
Jets represent Ipswich/SW Bris and Firehawks represent Logan/SE Bris.
I'd like to see Easts and Redcliffe join their bids together, like Jets and Bombers did, so we can get a good spread of 3 teams for the Greater Brisbane area.
South Brisbane Jets (Ipswich, outer western suburbs of Logan and Southern Suburbs Magpies District) and East Coast Dolphins (Eastern Suburbs Tigers District, eastern suburbs of Logan, Redlands, Moreton Bay). Broncos can focus on Western Suburbs Panthers District, Northern Suburbs Devils District) and Darling Downs as the "Broncos" theme appeals out that way where plenty of people have horses.
All 3 Brisbane teams can play out of Lang Park, with maybe 2 or 3 games going out to regional areas like Sunshine Coast or Springfield.
Five teams would make a "Queensland Division Trophy" a mini competition within the NRL, with each match between the 5 Queensland clubs counting for something and ensuring fans have something to look forward to winning, regardless of whether their teams are a chance of winning the NRL Premiership. All five teams play each other home and away, with the winner being the team who wins the most matches or has the best for and against if wins are even.
