Yes, IELTS is mandatory for an Australian student visa in most cases because the Australian government and education providers need proof that students can understand and use English properly during their studies. This explains what the use of the IELTS exam is, as it confirms a student’s ability to attend lectures, write assignments, and communicate in daily life. Many students ask what an IELTS course is because it prepares them in listening, reading, writing, and speaking skills required for study in Australia. Why IELTS is important is that it is the most widely accepted English test by Australian universities, colleges, and visa authorities. An IELTS qualification is usually required with a minimum score of 6.0 overall for most courses, while professional programs like nursing, teaching, or healthcare may ask for 6.5 or higher. Although some institutions may offer alternatives, having a valid IELTS score makes the Australian student visa process smoother, safer, and more reliable.
