Yes, you need to take the IELTS to study in Australia. Many universities in Australia want proof of English skills, often through the IELTS test. But other tests, like TOEFL iBT, PTE Academic, or Cambridge English (CAE), are also okay, especially for students from the UAE. The score you need changes based on the school and what you're studying, but usually, an IELTS score of 6.0 to 7.0 is fine. If your score is not high enough, you might need to do an English course first.
