Agree with the other guys MHCS re Suncorp. The map that shows up on the screen (which appears to show big parts of various sections as still available) is very misleading. I personally sat and looked through the various sections on offer and the large majority are 99% full. I'd estimate that there is about 45k sold.
I'd guess higher as at today. (Btw: The record crowd for Suncorp was 52,499 for BIL 1 2013, but SOO 2015 beat it out at 52,500 (funny about that perfect number). The Suncorp crowd for the Wallabies v England Test of June 2004 was 52,492.)
The complex part is that there are many sections (aside from Members') on Ticketek for this Test that have never been available and they are presumably UK and Intn agents and Aus agents and group sales, these have the potential for at least some 'returns of unsold' around now that then come back on Ticketek, although most of the UK-originating tours for these Tests are listed as sold out.
Assuming no significant levels of 'returns' and looking at the relatively small numbers of tickets available today - there are sporadic singles, very small clusters of Gold and a few Bronze clusters up on high (mostly in the Southern end), I'd say if the match was today the crowd would be close to 50,000.
Assuming more media attention in the next 10 days, a good walk-up crowd and good weather (Accuweather for June 11 extended forecast is for sunny and clear, 24 deg C), I'd say a sell-out for Suncorp is now more likely than not.
Which if so will of course ensure Brisbane has the biggest crowd of the series
