How to Book JAL Flights using Qantas points if not listed on the Qantas site?

Just trying to find out how to actually book Japan Airlines flights using Qantas points, when the flights are not listed on the Qantas site. I have confirmed that award seats seem to be available by using other program booking sites, but cannot book using those sites as I only have Qantas points?
Thanks in advance

You have to call Qantas to book these flights as its not bookable online.

There will also be a charge “Award Assistance Fee” 6000 points per passenger or $60 per passenger which is quite expensive!

Try to mention this is not bookable online and they may waive it. Worked for me before.

good luck
