Moving From Australia to Switzerland (Zurich)

I need help finding information on moving to Switzerland from Australia!
My fiance has been living in Switzerland since April Protected content , he moved there for a job and the contract is open ended so may be there for many years. I stayed in Australia because I needed to have an operation before I could relocate and also to work and save as much money as I could before leaving.
I don't speak a lot of German and I don't have any formal qualifications. We haven't set a date for the wedding but it is likely to be in the second half of Protected content . I am looking to fly over in the next month or two. I know you can enter the country for 3 months in a 6 month period without a visa, but i am looking to live there with my partner, not just visit. Does anybody know what Sort of visa I will need? Alternatively any tricks to get around this problem eg, having addresses in different regions? Anyone who has been through a similar experience? All help is greatly appreciated! And if you need any more information please ask :) The whole thing has me a bit lost!
