ni hao ma. i would like to come look for work in China..in fashion. do i need get a business visa

You need a letter of invitation from a Chinese company/unit or a letter of reference from an Australian company/unit to apply a F visa. Other documents are as following:
(i)Original passport with at least two blank visa pages and a photocopy of the current passport (photo page only). For single entry visa, your passport should be valid for at least 6 months;
(ii)One completed Visa Application Form with a recently-taken passport photo affixed on it;
(iii) copies of recent Chinese visa with entry record.

Hope you get the visa successfuly! Also best wishes for your getting a job in China!
