Studying overseas

[astroboy]

I live in Australia and eventually would like to do some post-grad study overseas, but many institutions are quite costly (especially for international students). Would anyone be able to point me in the right direction to those with full scholarships or those with teaching assistantships (I think that's what they are called). I know I should probably choose somewhere where there is a good teacher for me etc etc but looking down this avenue shouldn't hurt. Cheers!
