看了一下楼主申请的这个Established Business in Australia (Subclass 845)
实际上这个签证很多人都可以申请
Appropriate visa holder
You are the holder of a visitor visa, student visa or temporary resident visa, which is not a special purpose visa, border visa, diplomatic visa, domestic worker visa or transit visa.
学生签证、工作签证、商务签证都可以
但实际上这个签证绝对不容易申请,为什么,请看下列要求:
Significant assets
Your (or your and your partner's) total assets in Australia for the 12 months prior to applying were greater than A$250,000.
Ownership interest
You have held an ownership interest of at least 10% in up to two main businesses in Australia for at least 18 months immediately before you apply.
Business assets
Your (or your and your partner's) total net assets in your main business (or two main businesses) in Australia for the 12 months prior to application were greater than A$100,000.
其次要证实申请签证前12个月内,你所投资的主营生意内,你或你与配偶共同所有的总资产不能少于10万澳币,也就是接近54万人民币。
