Is Australia a good option for me to apply to given my large gap in education?

Yes, Australia remains a viable option even with your 48-year educational gap. Australian universities consider professional experience and personal growth, not just recent academic history.

To improve your chances:
- Clearly explain your work experience and reasons for returning to study in your Statement of Purpose.
- Highlight any recent courses or certifications to show ongoing learning.

For the student visa, you'll need to show genuine intent to study and meet financial and health requirements. A well-explained gap can help both your admission and visa process.
