Where should i go for year 10 work experience?

I'm live in Victoria and i am currently in year 10. It is come to the time where i need to find a place to do a week of work experience. I don't have a very good idea of what i want to do once i leave school but i was thinking about somewhere in the area of Astronomy or Astrophysics. Does anyone have any ideas to where i could go for something like this?
