As you know, Wynand, Qualiflyer is offering a free F-Class ticket ZRH-KUL (LX 4310 operated by MH) - ZRH for 160.000 Qualiflyer miles. What I really donīt know is, if a seat is available on the specific date you need it
Going for a free F-Class ticket to Australia for 280.000 miles (expensive), I would choose LX to HKG and continuing to SYD on CX (knowing that it is also very difficult to get a F-Class award seat on CX).
