Evening v Weekend

While the NSW Championship attracted a small field, the Ford Memorial Tournament held at the North Sydney Chess Club attracted a field of 65 players. Therefore a question that should be asked is "Why is the NSW Championship held on Weekends?".
Indeed, is there any sense in holding multiple week events on weekends? I could see the point of team events being held on weekends (for team travel reasons), although NSWCA Grade Matches are held on weeknights!. For individual events this makes less sense.
The ACT has always held its championship on weeknights, with the event usually rotated between the various chess clubs in Canberra. Of course the ACT is much smaller than NSW, making travel easier, but the NSW Championship is hardly ever flooded with players from outside Sydney.
The benefit of having the championship at a weeknight club is twofold. Firstly you save money on hire costs (assuming a friendly chess club is hosting) and you already have a pool of players ready to enter the tournament. A NSW Championship at St George or North Sydney would attract 50 to 60 players, even before non club members were considered.
Of course I haven't considered the problems with such an idea, such as inconveniencing players from outside/edge of Sydney or whether Sydney clubs are interested in such an idea. But overall I'd assume that players are more likely to sacrifice one evening a week, rather than one day a weekend.
