How to apply for IELTS exemption for studying in Australian high schools?

According to IELTS, there is no requirement for the applicant's English level.

According to the policy, in order to be exempted from IELTS, applicants must first obtain a junior high school diploma and graduate with good grades, with an English course score of not less than 75%;

Secondly, it should be submitted by the study agency nominated by the educational institution where the student intends to attend the main course. The number and quality of visas submitted by the agency must meet the requirements of the Australian Immigration Bureau. Generally, a certain number of applicants are required, and the success rate of visas is over 70%.
