You often assume that hi-tech and high budget observatories are fully automated. Well, not so. Remote observing has only just started at Parkes; with some folks from Swinburne happily going to be running their observations from Melbourne in future. There are still staff at the site in case they are needed, but the days of people flying out to observe for a few nights are probably gone.
At least with fewer students and grads around the observatory it'll be less likely to fail to operate because someone left the gate to the dish open, or had the wrong receiver plugged in
