I suggest you provide the following materials:
1, deposit 50,000 yuan.
2. Securities
3. Vehicle registration certificate
4, leave certificate (issued on the company stationery, including your annual income, position, entry time and leave time information. )
This is the material of assets, and other basic materials can be downloaded from the website of the embassy for reference.
Need to remind you that you are advised not to stay in Australia for too long, because normally speaking, you can't leave your job for too long in China, and it's not good to apply for too long. It is recommended to apply for about 7- 10 days (corresponding to the time on the leave certificate). The visa will take at least one month, and you can stay for a few more days if you want.
Good luck! Hope to adopt!
