whoops, didnt answer your question before.
This is my second season in Div III, I had one full season in Div 4, and about 3 games of the previous season in Div 4.
So overall, ive played two full seasons of BB. I only ever made the semi's of Div 4 season though, but got promoted regardless, which is ok. its been ok. As long as I dont get demoted, all is well.
I think shepparton has been in Div III now for 3 seasons, including this one. you can look at 'team history' on a teams page, to see how long they have been around, see how well they have done.
