Studying in Australia,South Korea, or Japan?

hey guys!!
im an AP student currently preparing for uni applications. I am interested in applying for Computer Science.

My plan was to study at Australia and do a bachelor of compsci there. however, ive heard more and more students choosing to do uni at top South Korean or Japanese unis.

I am not fluent in Korean, or Japanese, only english. I do know korean basics and reading aswell

Please let me know the pros and cons, validity and student life for all three so I can pick one of them!! Furthermore, the womens safety in these places, as I will be going alone.

greatly appreciated!
