Looks good. Only gave the document a quick perusal, what stage of development/approval are they in? Brothers have alumni in pretty much every major industry and government department in Brisbane, I wouldn't be surprised to see this fast tracked.
I think it's great, Brothers have a great junior rugby program with lots of supporters, this will make it much easier on them as it has been mentioned the grounds aren't great for viewing currently.
Speaking wholly as an outsider (although I have family ties to Brothers) - does getting a schmick new ground and facilities weaken that age old Brothers aura/motto of Us vs them? My understanding is they have never had the nicest fields or facilities but banded together as a tough bunch of pricks. If these plans go ahead they'll have one of the nicest rugby setups in SEQ and teams will be dying to get a chance to play here, with lots of away supporters coming along as well no doubt to check the place out!
