They had a 43k average for precisely one season...
Greetings LU. Been lurking for years, didn't imagine that I'd eventually break my posting duck over QE2, but here we are. t-ba, you're better than this. This one's gotten under your skin and things have become erratic.
The reality is that the Broncos from inception drew good but not huge crowds. Knights outdrew them in 88 & 89 (and again in 98 as they celebrated their first title). Brisbane footy fans were split between supporters, haters (for killing the BRL comp) & undecided. And old Lang Park was a good place to be for only about 60% of its 32k max.
The combination of the 92 premiership and the move to the big capacity QE2 in 93 saw crowd numbers explode. The first 3 years at QE2 posted crowd averages the game had never dreamed of. They were the 3 biggest ever right up until last year.
Then the super league fiasco did indeed smack the numbers back down to previous levels around 20k. And there they stayed until the flash new Suncorp arrived to help get the norm back over 30k.
Very short form Broncos home crowd averages from 1988 (launch) to 1997 (super league) --
16k, 18k, 23k, 19k, 22k, 43k, 38k, 36k, 24k, 19k. 1st 5 at Lang Park, next 5 at QE2.
tldr: Location of the ground was never the big issue. Everyone catches a free bus anyway.
