I understand what you are saying as the west side at Parra appears to have a bit less seating than the west at QCB (both have all the corporates on the one side, but QCB looks to have a bit more general seating in the west).
i just went and did a count on ticketmaster and ticketek and the rest of the lower bowl at Parra is 16 rows vs 14 at QCB, and upper is Parra 27 vs 30. So essentially they're pretty much the same bar the north end at QCB which is only 1 tier. This is why i can't understand the crowds announced at Parra at times, the top tiers look very sparse for the crowds announced. I know people stand at the back of the lower terraces so it might be a lot more people in those areas than I previously thought.
I cannot wait to visit it when I get the chance, this year I was pencilled in for the Cowbs game but work got in the way. The old parra I spent a lot of my teens years at in the mid 90's as my dad worked up the road on weekends. As a kid that grew up in NQ, having the chance to get dropped off and sit there for 6 hours on a sunday to see all 3 grades of top flight footy was absolute f**king heaven.
