Visonary I think the point is although your thoughts have merit. How do you think you are going to fit games into one venue. If we currently play one women's one men's game each sat night across five venues. starting at 6.30 for the women's men's finishing about 10.30 where can you fit another two games in do we start and 5 and finish at 1? and run two womens games and two mens games? Using Adelaide Arena (dome) as an example you could run two games on court 1, two on court 2 in the current 6.30 - 10.30 time frame but your specators will be sorely lacking by running two courts you lack side on access for specators. Using wayville court 1 would be fine for specators but they would struggle with seating on court 3. then you would lack warm up areas.
to run as many games as you want in a few venues you would have to shorten the games, less warm up time, less half time etc and lengthen the program.
If you are suggesting using only a few venues and only putting games on each week in those say AA, Wayville, Pas, MV and Plex you would be favouring southern suburb people in distance travelled to venue also give home court advantage to the teams that play in those venues.
The old format of women on tuesday night on show court at AA and men on wednesday night worked well, hoever even with three games there, and two games at then Forestville stadium meant a late night but there was a lot to be said for that in terms of specator numbers. However it was to remain on weekends do you play women on saturday and men on sundays?
