Kelly,
The reason I have included this is the fact that all EBAs in Australia are different and the allowances included make a big difference.
The QLink EBA does not include leave loading it is factored into the base salary. QLink does not have DTA, meals are provided or claimed separately by the crew (except breakfast which should be paid automatically).
DTA adds a substancial amount to the base in the case of Rex so should be included if talking about what you will live on when working for the group.
Rex can also claim meals and accommodation allowances in certain circumstances.
Both operators allow salary sacrifice for items such as computers and vehicles.
Most of a Qantas pilots income is made up of allowances and an hourly rate of pay. It also means the harder you work the more you get paid rather than a flat rate for all work up to fatigue limits.
