Ozstamps - Efrem is talking about the US issued Centurion (otherwise known as Black) card. The membership rewards points don't count for status miles, but holding the card per se makes you middle tier elite on DL, CO, US (and possibly another one or two). I.e. if eligible, for the annual fee of $1000, you can buy elite status. I don't know if Amex offers Black in Australia and if so what benefits apply - the UK issued Black card does not give the elite memberships.
