You could do AMS-LHR-HKG-BKK for about £650 one way, then try to pick up BKK-KUL-SYD on MH (has been £600 ish in the past), followed by SYD-SIN-LHR-OSL for about £1,200. (The AMS-BK and SYD-OSL legs would need to be on the same ticket).
That lot would get you 880 TPs and you could fly via MEL for about the same price and an extra 40 TP.
There can also be lots of other good earning opportunities in the region on MH from time to time.
No current MH sales to allow you to do that, unfortunately, hence I'm planning to use avios for KUL-AKL next year.
