What are the legal requirement to start a catering business at home in sydney?

ya know i tried this when i was little(young)well aside from all the home catering,small business courses ect,it's really hard,it is so very involved..NO,you can not just cook good,gourmet food from home,There are all the health&safety guidlines&laws to learn&follow.An industrial kitchen(industrial/proper catering)equipment will be installed(not allowed to just cook on your stove)food poison issues(we had to learn all these different acts/liscencing ect)Even just to provide food for lunches(sandwiches for school/office) ect,if it is to come off your premisis&be consumed by others(public)it is not that easy(no such thing as you make it&they consume it)not without 20middle men!Obviously you will need to get the facts&health acts(fire safety)I did some home catering courses(in Papua new Guinea)through STOTTS COLLEGE(australia)they had all this tpye of data(as that was the idea..open my own home catering)well there was so much fixing that had to be done(oh&you actually need to have kitchen space off your property/had to be industrial)(will have changed by now)that i gave up(was easier to work for some other chef!!!!! I know i wasnt much help,just wanted to let you know,it's hard,they throw up so many roadblocks,so good luck&enjoy the research(so many laws to read&know/by letters&numbers ect)
