Curious to know why you'd want a Centurion ..... it is a card directed largely at those for whom luxury is 'their style'. The card would appear to offer you nothing other than the extra points earn which is of marginal benefit given the additional cost over Platinum.
Platinum seems a better fit
I think 3 things attracted me:
1. self-recognition - read about this card when I was young, and want this card all along my business journey since came to Australia at 20, and now 20 years past, I have achieved one and another, this is one of my goals, want to get this done.
2. travel booking concierge - want to see if they could book a series booking for us to achieve value for money, normally we need to book 6 months ahead at the beginning of the year, and mid of a year for the second half - flight, hotel, vehicle for multiple members that is business travel, very time-consuming, and sometimes, once flight changes, we are rushing to change next series booking, pressured, want to have someone to assist, especially when on travel.
When for school holidays and holiday booking, that is even worse, sometimes we need to book for big family international travel for gatherings, sometimes up to 26 people flight bookings, like a travel agency's works..... I was thinking Centurion concierge to handle this for me. I am thinking of using Amex business travel brokerage service as well if I cannot get Centurion in a short time. Of course, I don't use first-class flights myself, but I will still book first/business class for my parents. And all the premium travel services of course for them only.
3. There is no other premium card in Australia at the moment to compete, if we were in the US market, I would not really be that fascinated by the Centurion card, so many other options, but in AU, we only have this card provide this service, what other options we have?
