1. In Sydney, only two schools in the GPS and CAS competitions DON'T have a cricket pitch in the middle of their no 1 rugby fields: Joeys and Knox. Knox have done a magnificent job over the last few decades setting up their no 1 field with terraced seats on the western side together with substantial lighting for night games. Joeys set up their no 1 field on the north-west end of their playing grounds, which is on half of their no 1 cricket oval. What you probably don't know, Sofit, is those temporary stands on the south-eastern side of the no 1 field are on the no 1 oval cricket pitches. Putting up more substantial stands on that side in winter and taking them down in summer could prove to be problematical while not damaging the pitches.
Yes, the main Joeys stand could do with an update. I suspect Joeys will get around to that task in the immediate future. Installing lights to allow play at night-time has been continually stymied by local residents; they'll win that war one day. BTW, have you seen what Joeys recently did with their swimming pool? Can't do everything at once.
