A little late, maybe, but in Nov 2014 ex-SIN:

SIN - KUL - SYD
MEL - KUL - SIN

Bid minimum of s$50 and s$300 for each SIN-KUL and KUL-AUS legs respectively. Got accepted on all except the MEL-KUL leg.

The SIN-KUL upgrades - flight itself really quite pointless, but I bid for access to the lounge.

Blogged about it here for anyone interested.
