There was a pretty good model to follow from when Sunnybank stepped up.
From memory they had 1 year in reserve grade plus( 3,4 and colts 1,2) then the second year they had a full compliment 1st, 2nd, 3rd, 4th plus 3 colts (no womens anywhere in those dim dark days)
It took a bunch of committed people and a bit of work to get it up including inducing a couple of seasoned fellas to move over (a prop from wests comes to mind), but in the end they now have a very solid operation that ebbs and flows with all the clubs.
If the folk up in the sunny coast want to miss out thats fine, I am sure there are opportunities elsewhere ( Ipswich, Toowoomba, Springfield, Redcliffe areas come to mind given the growth of old brisbane town)
