Home transport for Long Range Flying is the same for QAL and QCCA. The hourly salary rate is different but the triggers for over time on those rates are the same. ie 12 hours and 14 hours.
The other main difference is that QAL crew get a Long Range Allowance that dates back to the 1980's and the introduction of the 747-SP.
Meal Allowances in Slip ports are the same for all Qantas Group International Flight Attendants (ie London/Auckland/OZ crew and QCCA)
