JASON is a search engine that contains information about postgraduate scholarships for Australian students wishing to study at home or abroad, and for international students wishing to study in Australia.
Full scholarships are available through the Commonwealth Scholarship Plan, for Commonwealth students to enable them to study in other Commonwealth countries. Grants are for one to three years and usually cover the cost of travel, tuition fees and living expenses. It is likely that the scheme is aimed more at students from developing nations, but have a look you may qualify.
