[TD] You must provide one of the following:
evidence that you hold a passport from Canada, New Zealand, the Republic of Ireland, the United Kingdom or the United States of America
an IELTS result showing you have a band score of at least 6 on each of the four components of speaking, reading, listening and writing
evidence that you have taken an OET language test and attained a score of at least B in each of the four components of an OET as specified by the Minister for Immigration and Citizenship.
