PAF- if you do the maths the difference isn't significant.
Assuning same stick hours (which would be the case on 737 and 767 and A320 domestic ops) the difference in crew costs between J* pilots and QF pilots is about 0.1 cents/ ASK. That means for SYD-MEL the price difference is going to be about a dollar. For SYD-PER it is going to be about $5.
I'll leave it up to you to decide if prices will go down!
