Another update so soon after the last one! Everything is happening all at once!
I realized the other day, after receiving my confirmation of my place at Grenoble, that I hadn't applied for my visa to travel into Australia. What followed was a massive flurry of panic, when I worried that I wouldn't have enough time to apply and get my visa approved before I would buy my flight tickets! Luckily, when I researched on the Australian visa site, the visa I needed was all done online, and only took between 2 and 10 days to approve. After applying on Wednesday lunchtime, I got my email today stating that I had been approved for my eVisitor visa, so I'm golden to travel to Oz! (They must have decided that I didn't have a dodgy record, and didn't look shifty enough to deny entrance.)
