How can I find if there is business class award availability?
I don't think you will find any availability. As far as what we can tell from the communications, this is a codesharing arrangement with reciprocal lounge access arrangements for Flying Blue and Qantas Frequent Flyer passengers. No mention of KLM becoming an award redemption partner at this stage. To get to AMS, you will have to look at AY, EK, QR, CX or BA.

What a shame. How about the Air France codeshare to Paris?
I wouldn't be rushing to book this. I've done the continuation sector SIN-DPS a few times as its excellent value and always feel sorry for those doing the 11 hr haul. Entertainment is very limited for English only and seats beyond the front few extra legroom rows are pretty squeezy.
