The Qantas Premier Platinum Card delivers up to 100k Qantas Points, 75 bonus Status Credits, complimentary lounge invitations and travel insurance. All this with a reduced first-year annual fee of $199.
The points calculator is the place to start, but unfortunately for you it does not yet include Sri Lankan. You can plug in SIN - CMB and choose CX to trigger the partner earning levels. For that leg you will get 80SCs in J and base points of 2132 for Bronze and more for other tier levels. CMB - FCO/CDG don't come up and won't until Sri Lankan and its destinations are added to the calculator.
