Hi Loz,
I'm also a female Uni student in Australia. I've been on Atkins for the first time for a week and one day (and counting!). I haven't told any of my friends that I am on Atkins. I guess it will come out eventually, but I don't want them to make a big deal about it.
Good luck with your goals. (I find it really hard working in pounds, etc!)
