Let's compare apples with apples
Very few (if any) QF -400 SOs are earning over $160K a year. As Mustafagander said, $150K is closer to the mark.
This figure includes divisor pay/overtime, DTA and allowances. Therefore, to compare QF and CX pay objectively then perhaps housing allowance, 13mth pay, profit share (!) etc should be added to the CX base pay rates.
FYI the COS 99 base pay for a first yr Oz based FO is $118K but then adding hourly duty pay and super takes gross pay to about $145K. Meal allowances are additional to that, but are generally less than what QF pays.
