I am in Japan now, and I want to go to Australia. Can you give me some advice?

First of all, I don't quite understand what you said about going to Australia, whether it is immigration or visiting relatives.

Consider yourself an immigrant. First, your cousin's green card in Australia has little to do with your immigration to Australia. In other words, she can't help you because she is not a close relative.

To find an offer from an Australian company, only you or your cousin can help you find some private bosses and come with the employer's guarantee. Generally speaking, it is a visa to work. After a few years, you can apply for it yourself. But do you have any special skills? Like chefs, haircuts, car repairs and so on? If there is nothing, it will be even harder.

If by automation you mean running your own company, you might as well take the road of investment immigration. Two years of management experience, plus more than 250 thousand Australian dollars in fixed assets, is basically enough.

If you want Australian companies to recruit you in the past, it seems more difficult, so you can only let your cousin pay attention to the local recruitment information.

Anyway, good luck!
