Based on my IELTS score, which countries would be better options for study abroad—Australia, Ireland, or others for a Master's?

Ireland is a better option for your current IELTS score of 6.0, as most Irish universities accept this for master's programs.

For Australia, most universities require an overall IELTS score of 6.5 (with no band below 6.0) for master's admissions, so your current score may not meet their typical entry requirements.

To expand your options, consider retaking the IELTS and aiming for at least a 6.5. Some universities may offer conditional admission or pre-sessional English courses if your score is slightly below the requirement.
