I'm pretty sure you do get the living away from home rate for youth allowance, but you'd have to double-check.
Is is really quite social. On an average day I'll spend the morning either working or going to class, have lunch at college and talk to people, spend the afternoon either working or going to class again, have dinner, spend the rest of the evening watching a movie/TV shows or going out. I've been walking less into civic at night because it's so cold, but now that it's Spring again it'll be good. On a weekend I work all day, have dinner and fall asleep during a movie. Thursday nights are for going out if you're into that.
The food is meh. Some days are better than others. I have gained a little weight (I think about 5kg over the year) but that's also partly because I've recently had a bad tendency to snack on things during the day and as I mentioned earlier, I haven't really walked as much because of the cold. I think that having at least 2 hot meals a day is offset by all the walking you have to do if you go here (it takes me about 10 minutes to walk to Manning Clark from Burgmann and if you do that, there and back, twice a day, that's 40 minutes of walking; then walking into civic takes about 20 minutes, so there and back is another 40 minutes, which I might do a couple times a week).
