Airlines, Airfares, The Lot [aiyoh...headache already lah...]

As many of my mates will know, I went back to Malaysia last year for a week on a very impromptu visit due to my move to Perth, WA. =)
Of course, because of this, they also know that I will be unable to make it back to Malaysia till next Christmas. Also due to my Matric, this being my last year, I need to study and study hard to procure my entrance into university.
My mom, (being somewhat horrible, I believe, but oh well, I guess I should get used to it now) is also making me buy my own airfare back to Malaysia, and I have agreed to do so. I have to also ensure that I get back in time to ensure that everything is well and done for my university entrance and that there are no glitches in my First Year of University.
So, for the past hour (and for many more days besides) I have been looking for the cheapest flight.
The cheapest flight, I have thus ascertained, would be via Air Asia. The return ticket comes up to about A$250, which is bloody cheap, to me. =) My only problem? The stupid Air Asia flight only lands at the Gold Coast in Brisbane. (Grrrrrrr) I checked out (most) available domestic floghts. And guess what?
The domestic flight ended up being almopst A$300 and MORE. For one bloody domestic flight to Brisbane! Honestly, why is the domestic flight more expensive than the international one is my question???
So then I checked out Malaysia Airlines. It's a direct flight, but the ticket tops up to about A$800. It seems alright, but compared to the A$600 I'd have to pay for Air Asia and the domestic flight, it's still a pretty high price. Of course, there's no actual gaurantee that I will end up getting a A$300 flight to Brisbane, I may end up with a A$400 one, but still, that's possibly the lowest I can get, even though I incredibly DISLIKE the idea of the domestic flight being more expensive than the international one.
So then I checked out Qantas Airways, which is an international flight, and I hoped that it would get me there directly.
Wrong move.
I checked it out with great interest and found, to my intense horror, than this stupid well known international flight only landed at Sydney. AGAIN! I would have to end up making another domestic flight to Perth in order to get back. (Maybe I should just stay in Sydney, is this a sign to me?)
So yeah, either way, NOT happy.
I would gladly try using Singapore Airlines, but I soon found that Singapore Airlines was even MORE expensive than Malaysian Airlines, and soon gave up the idea. Singapore has a really cool airline and all, but nah, the price isn't worth it till I become a multi millionare, selling my book containing advice on international airlines and their services and airfares all over the world to great travellers like myself. XD

Ah, the woes of a traveller! XD
