Hi,
I don't think there are big differences between Australia and New Zealand.
Don't know about Australia, but in NZ the current international fees (those for Students from Overseas) for studying a 4 year Bachelor of Health Science/Physio are NZ $ 32.000 per year.

English language requirements need to be confirmed; there is a variety of tests available. The IELTS is the most common one.

Hope this helps,
Fyzzio
