While it's possible to apply for the February intake in Australia in October, the exact application deadlines can vary depending on the university and the specific program you're interested in. Many universities have application deadlines around 6-9 months before the intake, which means you should ideally apply between April and July for the February intake. However, it's essential to check the application deadlines for your chosen university and program, as some institutions may have earlier or later deadlines. Applying early gives you a better chance of securing admission and obtaining a student visa in time.
