You've come up with a solution to a non-existent problem.
There is ZERO evidence of any decline in the popularity of Origin in crowds or TV ratings.
Having it annually in Brisbane and Sydney makes it an event and only increases demand and interest in those markets. The exposure it creates in the non- traditional markets is in turn driving its popularity even more.
Not sure you understood what I typed! I’m saying that take it to perth, Adelaide and Melbourne on a 5 year cycle then the other 2 years 2 games would be in Sydney or Brisbane rotating. having a gap in non rl cities means it’s remains a rarish event to go to, go to the well too often and it’ll run dry.
yr1 Sydney, brisbane adelaide
yr2 2 games Sydney, brisbane
yr3 Sydney brisbane, perth
yr4 2 games brisbane, Sydney
yr5 Sydney, brisbane, melbourne
repeat….. presuming non rl state govt’s are willing to keep buying it,
