I think you misinterpreted what I'm saying. Oakey are entitled to do whatever they want with their airspace at anytime of the day or night so if they want to restrict it then that's their choice. I am a local twin engine aircraft owner too by the way.
There are plenty of aircraft that still use oakey on weekends for approaches and the like. I also note that a silver R22 does hot laps of the airfield at about 10ft on weekends too.
