39,000 actually.
Being 57,000 pp for QF J, minus 18,000 for JQ.
But that’s the absolute minimum refund and would be due under Australian Consumer Law anyway.
The point
@trippin_the_rift has made is that there should be additional compensation for things like the inconvenience, no IFE, arriving ~16 hours late, being stuffed around at the hotel because QF didn’t pay for the rooms they booked.
Plus there’s the time, effort and hassle of having to chase QF for the refund which frankly should be automatic.
