You may or may not know this but if you are doing a couple of trips a year to Los it might be worthwile going one way with jetstar or Tiger (Mel and Per) and then buying a Singapore- Mel_Per- Return. You can pick up a Sin-Per_Sin for $298 Sin$ or about $260 Aus including Taxes!!!!!!!! Using this method if you bought the following :

Per - Sin about $300 AUD with tiger
Sin - Per-Sin about $260 with Qantas
Sin -Per- Sin About $260 with Qantas and don't use the return leg you could have two return trips Per Sin with a lcc connection in Sin to Los. Total Cost $820.00 AUD. + Sin - HKT/Bkk

Go to the QF singapore website and you will find these ridiculously cheap fares. But why not available to Aussies in Australia?

I'm flying at Easter with Tiger Per-HKT $900 AUD
