Ask HN: Any tips on how to spend my semester abroad?

Hello HN!

On Wednesday I'm going on a semester abroad to Perth (Western Australia) until December. Until now I was not quite sure how I should spend my Semester abroad. Now I've got this idea of using the semester to do a lot of sports and live as healthy as possible to prevent any diseases that might be caused by future stress I will probably have to face when joining the labour force. As I was told that the academic level will not be too high I should have enough time for that.

Do you have any ideas or experiences what I should additionally do to to gain as much positive and sustainable effects out of my 4 months in Western Australia?

Thanks :)
