I booked a reward flight to SYD only last week. On the M&M website you see quite a lot of flights, mainly to SYD and MEL (haven't checked other cities), but only from the major hubs like FRA, MUC, ZRH, and VIE. These are bookable via the website, despite being a 3-region-award and also for a lot of partner airlines like SQ, TG, OZ, NH, CA. I found my flight from MUC on the website, but had to call to add a feeder flight from TXL to MUC, that was done in 5 minutes.
