Perth - Darwin West Coast road trip!

Hey,

I'm flying out to WA in the next two weeks with the intention of going
up/down the coast from Perth to Darwin or Darwin to Perth. I'm
travelling alone, and trying to make the trip as cheaply as possible -
hopefully sharing lifts with other backpackers along the way. Is this
easy to do.. are there many lifts up or down the coast?

I'm currently thinking of starting in Perth, but I believe that
relocation vehicles are available in Darwin to return to Perth, which
would obviously increase the number of potential lifts down the coast.
I guess if all else fails I could hire one myself for the journey, but
I'd prefer a few weeks to do the trip rather than the 9 or so days
they may insist upon!

So.. should I go Darwin-Perth, or Perth-Darwin? Are there many
buses/tours between these two places also. I have to complete the trip
in no more than four weeks.

Cheers
Tom Evans
