Nah they just have set more sections for general admission.
So say each bay has 500 odd seats. When in GA form they only sell 90%, so that there is space to move around, etc. People are too pathetic to sit next to others unless forced.
You should have seen vs the Cowboys last year, the GA bays would have been 70% full, if that. But were "allocation exhausted".
As the season progressed and the ushers at Suncorp became a little more comfortable with bossing around patrons to sit where told, the sections started to thicken out.
I remember looking across to them for the Bunnies ANZAC day game and saw so many holes. This game was all sold and selling restricted view (about 2,500 seats), and the crowd was 44k, with a PAX of 49k.
Our main problem at Suncorp is the horrid members, Stadium members treat it as an accessory, just a bunch of corporate partners that LOVE everyone to know that they have one, you know. The fat and greasy type, resemble and egg roll. They only come for Origin and Bledisloe matches.
