Getting refunded for medical condition?

Basically I was supposed to fly to Tokyo from Australia with Jetstar tomorrow but I ruptured my ankle ligaments and need to head back to France to get surgery etc. It was a non refundable flight, is there any chance that I can get refunded due to medical condition? Should I be looking into my insurance policy/my debit card's insurance?

I've been trying to find the answers myself looking at Australian regulations and it got pretty overwhelming so any help will be really appreciated 🙏🏽
