That must have been a long time ago Brian...Changi airport is one of the best I have seen.........Pal have changed that route now, don't remember exact details, but I think Darwin is cut out now..
Redhorse and Brian can confirm these Cebu Pacific promos to Oz at present as managed to snare a one way Manila to Sydney for June 2 with meal and 20kg luggage for AUD$149 but there is only a few seats on each flight within the booking periods so you have to move fast. Good point about possible scams Brian especially through facebook.
