Thanks. Interesting.
Any chance anyone knows the lowest limit for Platinum vs the Black. Edit: Found the answer: 15k vs 6k.
Reason is that theres existing Westpac Platinum Visa + Amex bundle:
Altitude Platinum | Westpac
And the platinum offers 75k for the 3k spend vs the 80k on the Black for the 3k spend. The amex 3k would be significantly tougher given not many places take amex so I've written that off.
