To close this one out: I called QFF today as a Bronze member and was connected to a fella in South Africa who found the reward flights and processed the booking for me without any telephone assistance fee.
Prior to this i had checked expert flyer and there were eight X class seats on the flight so i knew it would be a lock. Seems like restriction in the QF website.
No idea what is in Timor Leste but i will let you know mid January!
