How do I know that the Australian visa has been cancelled?

Hello, I'm glad to answer your question:

1: You can go to the Immigration Bureau in official website to check yourself. The specific steps are as follows:

A: Driving in official website at the Immigration Bureau.

B: Search for "VEVO", which is the abbreviation of "online visa authentication".

There will be "VEVO" on the left.

Click the first one below: online visa rights verification.

D: Click the first one on the right, "Check your own visa details with vevo".

E: By filling in the passport, date of birth and other information, you can finally enter the page of inquiring visa status.

I hope the above answers can help you, and I hope to adopt them. Thank you very much!
