In Australia/New Zealand, international students are *generally* funded by their supervisor. In Australia there are full Government-funded scholarship opportunities for International students, but I am not sure about New Zealand - you will have to research it. Try Google
Edit; supervisors/Universities from Aus/NZ generally wont expect you to pay for tuition fees or living with your own funds unless you offer to. If you get accepted it will most likely be because a supervisor can afford you. Alternatively if you are in good contact with a supervisor (before or after acceptance), they will likely tell you which scholarships to apply to.
I think the School/Department of concern would be far more appropriate to ask than people on the forums.
To clarify, I wasn't being narky - it is imperitive that you clarify that with the actual people who are asking for it, to whom you can simply send an email!
Well since you are asking for rankings - University of Melbourne or ANU

Shoot me now, ikr
I applied, no news yet... I've been wondering the same thing as you
Also, I think this belongs in Earth Science forum since it is Environmental Earth System Science in the School of Earth Science. You have some great opportunities for interview already (Harvard, Arizona, UMinn), so I wouldn't worry too much
