One of my best friends flies out of Perth Shorthaul .... They only do day trips, no overnights at all. PER-DRW-PER, PER-KGI-PER-BME-PER, PER-KTA-PER, PER-DPS-PER ..... from what I can gather that is it.
And yeah, the PER Longhaul flying is just as limited, and no - I spoke to my friend and they dont have enough Shorthaul crew to do their own flying at the moment, let alone take over Longahul's, but I believe they are getting some new causals soon, as they need to promote more CSMs....
