I think the "not available to everyone" is already covered by the invitation only selection. No need to do this via the annual fee. There is absolutely no justification why we in Australia have to pay so much more annual fee than members in other countries. I would be very happy if they dump Qantas Club and Priority Pass and the rather worthless SPG and Intercontinental status and reduce the annual fee by $1000. PP and SPG is already part of the Platinum card anyway, so no additional benefit.
Permanent CX Diamond or QF Platinum for airline status and SPG Platinum or LHW Unlimited for hotel status are in a different league and would add considerable additional value.
For the current personal Cent., one may ask to be invited, so it's not really invitation only. Obviously one needs to fill certain criteria.
I understand that Australians pay more than a few countries, but we also pay less than a few. The dollar amount, on its own, isn't a fair comparison - it's got to be based on the standard of living in the country it's offered.
Currently, Qantas Club may be purchased, regardless of the rate, so it's easy to offer that, long term. Status with carriers is much harder to negotiate, and carrys as many cons, as pros, for the airline offering the benefit. Barely does it increase sales for the carrier offering it - maybe for the alliance. CX Diamond is a nice benefit for Y travellers but its existence depends on annual negotiations. I doubt QF would sell Plat membership, but maybe since their premium route network is constantly diminishing, it will be considered, or maybe Amex will play DJ against QF to get one of them to offer Plat in the future. SPG has made it clear that Plat is to be earned, and I'm glad of that.
I agree that if it were truly exclusive, Cent would offer those, otherwise impossible to buy, statuses. Hilton is a small start on this, with a few extra points, internet, breakfast and tiny upgrades, on average, and this has a value of about $1000 to me, although the earned SPG Plat is of much higher value.
The conundrum is that is you really do travel a lot, or travel in premium classes, you don't need any of those benefits as you will earn the ones you use regularly, anyway.
I would love a rework of the benefits, too... but since we all value things differently, not everyone can be pleased.
If I have a complaint, it is the capped bonus points. Their value should, at least, match the cost of the card, so if capped at all, should be $900000-$1000000 in spend.
