A WNBL ticket is normally $10-$15 to sit anywhere. It's a considerable price increase if you paid that to sit behind the bench and now pay $20 to sit up the back of the WABC.
The WABC is a compact venue, so even bronze seats at half-court give you a good view. ANd they work out a smidgen under $15 per game. ON the elevated side there's maybe a dozen seats in the first block then the walkway, and on the other side its maybe 14 rows and the back couple are bronze.
Personally, I'd prefer Bronze seats close to half-court, than pay extra to be closer, but potentially further towards the corners.
The $400 memberships are really only for those who WANT to spend the money, get the "best" seats, t-shirt, priority parking, etc. You can get decent seats for only $160, or a silver Family membership for only $500 (2+2).
