opening a studio?

Hi guys, i was wondering if anyone has any insight into what your require to open your own studio in Australia or teaching privately from home or at people houses. As i mentioned in my blog the other day in england i was an assistant instructor but as my visa ran out i was unable to become a teacher. I really want to start  teaching privates back in aus and eventually open my own studio but the internet is not being helpful at all. In england all i needed to be a teacher was my own ABN for self employment,  a music liscence, insurance and a exersize to music cert. I am unsure whether it is the same for aus or if i need to have pole teaching certifications etc? Any insight would be great as i im trying to put my mind to good things atm !!! :)
