Curfew at YSSY
Having an international airport which is restricted to only 17 hours of operation per day is a bit like having an interstate highway only able to be used in daylight. As others have said, if the politicians had any desire to do anything other than get re-elected they would tell the complainants to sell up and bloody well move. There would be very few, if anyh, that have moved into the noise affected area that did not know there was an airport nearby.
