Are the baggage allowances the same on domestic, trans-Tasman and international flights?

When you transfer from an international flight to a Qantas domestic or trans-Tasman flight, or vice versa, within 24 hours on the same ticket the international allowance will apply to both sectors. If you are travelling on separate tickets you need to present both tickets when checking in your baggage. Some exclusions and restrictions apply. Visit Qantas.com for more information.
