There is a whole lot more to efficiency than the amount of hours flown.
It is the amount of deadhead sectors, the amount of nights in hotels, the amount of overtime paid etc.
From anecdotal evidence, i would suggest that QF L/H is a long way behind the 8 ball when it comes to roster efficiency compared to may of their competitors.
Additionally, as Chimbu says, some of you guys have your eye on the wrong ball. Your competitors are your enemy, not your fellow pilots.
You should be asking your management and the CASA why EK are allowed to fly through australia when they don't comply to the one day off in seven rule for instance. These are the areas where you are being screwed.
It appears to me that you are content that your agreement precludes you from having to work such arduous rosters, but as long as your competitors are allowed to, you are screwed. You may keep your conditions through some sort of industrial action, and win the battle. But if your airline has to compete with others who have a lower cost base, then you will eventually lose the war.
