Only a few years ago the 747 guys were all pushing the 900 stick hour per year limit. How is that so inefficient? Wage differences would not be enough to bridge the gap between Qantas on high load factor and yield versus Jetstar with lower load factors and presumably yield. The difference in fuel due to old aircraft and the bloated ground staff of Qantas [some of whom do Jetstar work on Qantas pay] does make Qantas inefficient.
