Will this couple's Australian tourist visa be refused?

Australia is a developed country and has a certain probability of refusal. No matter how good your information is, you may be refused a visa. If your own information is insufficient in any way, the probability of being rejected will be greater.

The Australian visa pass rate is related to the following factors:

Have you ever been to a developed country like Australia?

Are you married and have children?

Do you have a steady job?

Is your household registration a sensitive area?

These are the main assessment factors for visa officers. Of course, everyone's information is different, and the probability of refusal is definitely different, depending on your actual situation.
