Hello Miss Claire from an Aussie from the Eastern Suburbs of Sydney.
You've picked a pretty place in die Schweiz to work...you'll be speaking Swiss German in no time.
There are loads of Aussies here in Zurich. My tip: join the Aussies Abroad group to find out when they are holding events that you can join. I know that they meet regularly at the Outback Bar in Zurich. Not the real deal there, but it's a starting point to meet other Aussies.

Have a fab time.
