This is the first "platinum/black" card where I've seen you get 1.5 bonus points on Qantas spend, rather than 1 bonus point. From their T&C's.
"You will earn 1.5 Bonus Points for every dollar charged to your Card Account for the purchase in Australia of the following services directly from Qantas (ie. where Qantas, and not its agent, is identified as the merchant on the credit card transaction): Qantas flights, Qantas Club and Qantas Frequent Flyer memberships, and, purchases from 'Qantas Travel' customer shopfronts."
That means 3/ppd on Qantas flights, compared to the other black CC's which you'd just get 2.5/ppd.
The ANZ Black for $425/yr is nearly identical (their Visa gives you .25 more points), and you get ANZ Visa 'exclusive entertainment' offers for which I've received 1 in 6 months.
And this NAB is $250, 3ppd for Qantas, and has 24/7 as well. Looks like you don't receive Qantas lounge access through when you buy international qantas flights.
This would be marketed under the Black level as offered by ANZ/Westpac.
For starters there is a $25k points cap per statement period.
The extra 0.5 bonus points per dollar on QF spend probably won't make much of a difference to many.
75k bonus and $1500 spend is rather generous compared to other Platinum level cards.
