I had a friend try to get a FF ticket from Tokyo to Sydney, any date, nothing for the next 12 months.
I am not a supporter of QF, I wont "pay" for a ticket with them. I will use FF points, BUT there are seats every month from Tokyo to Syd in economy, premium economy and business. as of 5 minutes ago. (I selected the 2 x adult option) Those seats are available from Narita or Haneda.
With all due respect, reading this and your initial post, you may need some assistance with the booking process.
35,000 pys economy
54,000 pts premium economy
72.000 pts business all direct to Syd.
You also have the option of Jetstar (why would you) or Air Japan if you wish (I would go that option) +taxes of course using your QF FF points
