Just in case anybody missed it: I am back home! And I have been for a while now. It took several weeks to fully settle in, but by now I have my unemployment benefit and my health insurance back, got my Australian tax refund, my Australian superannuation refund and my package with excess baggage that I had shipped by sea which took a good 2 months.
Everything is running it’s course and I am currently in the process of getting everything ready for university.
