Also, if we're talking about the best use of QFF points, then I often book PER-SYD or PER-MEL flights as a cheap Red-eDeal, but first check to see if J awards are possible on the same flight. When the Y booking is confirmed, usually about 1-2 hours to receive the confirmation email, then I jump in immediately and upgrade the flight to J using my points. This changes a $300 flight into a $2000 flight, which IMHO is a very good use of my points.
