That visa looks like it's for someone who wants to go study and get a degree in Australia. I think either the Short Stay Activity (subclass 400), Work and Holiday (subclass 462), or Electronic travel authority/business visitor (subclass 601) would work depending on whether you will get support from your host institution (although I don't know for sure). They all take different amounts of time to process and the prices are a bit different. I emailed Rick about this but he just responded that we should coordinate the in-country support and visa directly with our host, which I find a little bit confusing.
For Australia, a few people have told me to look on the website http://www.gumtree.com.au/ which is basically Craigslist for Australia. I was hoping to find a place that way but haven't heard back from any places I've contacted, so I might do Airbnb as well. I was hoping to go in early July, I hope the timing can work out!
