i am going to Sydney on the 18th Sept.i stay in Singapore but i dun mind travelling to KLIA (KL) to depart from there. i dun see any budget flights from Sg or KL but i may be wrong.any help here would be great.thanks alot!

If I wanted to see Sydney and to come from Perth .what is the better way to go there-by train or is it a very long journey ,or by plane?

I've not decided where I will head for after touring Perth so maybe you can give me some suggestions. However, I'm not familiar with the types of budget airlines which provide domestic routes in Australia other than Qantas. Can you tell me which other airlines operate from Perth airport to (1) Sydney, (2) Melbourne and (3) Brisbane and (4) Queensland? Thanks.
