It appears that Woolies are now paying up to 1.15 cents for Qantas points as they are running with $10 of Woolies promo dollars equals 870 Qantas points. If you allow no room for a conversion margin then the most they pay is that 1.15 cent number.
Qantas are likely to want to get paid monthly so it would appear that Woolies would get an invoice for around $5 million to $10 million a month plus gst on the domestic portion of the flights used in Australia. Well that is what looks likely based purely on some arithmetic and guess work.
Citibank,CBA,NAB and soon ANZ (Feb26/27) will mostly be out of ATO points/miles earn. Westpac Black Amex points are being delivered at 0.75 points/miles per dollar so the cost recovery is about 1.93 cents per point/mile ( less any tax deduction value if applicable). That could be 1.75 cents pl calculationus gst of course and I think Westpac could recover the gst monthly.
Naturally it would be nice to get the guesswork checked but that is what I think could be the position.
If you take up a 250,000 Qantas point earn on a NAB housing loan then that bank would have to build in a way to recover almost $3,000 that would need to be built into the term of that loan.
