Have you ever tried setting up a hoochie? They're a pretty basic shelter, no more than a tarp, really, but they do have the advantage of being light, and not taking up much room in your pack. BTW, if you sleep on your side, as most people do, an inflatable pillow is a must-have item!
I don't use mine to support my head directly, but place it under my sleeping bag, where my head is going to be.
Check with Bunnings if you have one in your area: They had SIAMs on sale for under $40 a while back, and they may get more in next summer.
As for tents, these aren't bad, SW: http://www.snowys.com.au/Hiking/Hiking- ... =74&id=153
