Australia has multiple entry visas. I have been in the country for 2 months, and now I have to leave the country for 4 days. Can I stay for another 3 months if I re-enter?

Excuse me, are you applying for an Australian 600 visa? If it is this kind of visa, the validity period is generally one year, multiple entry, and each stay does not exceed 3 months.

In your case, there is no problem in theory, because the Australian visa is valid for one year and you can enter the country at any time; But from a practical point of view, I suggest you not to re-enter the country immediately after leaving the country. After all, you have applied for a tourist visa and you have been in Australia for 2 months. If you frequently enter and stay, the customs will doubt your entry purpose, and you may be refused entry by the customs.

To sum up, it is recommended to enter the country at a long interval.

The advice of the donkey friend, I hope it will help you!
