. Correct. I've actually done the 60 day extension off a spouse extension. I planned to go back to Oz and visit family and get fresh visa instead of another yearly extension. But wife was rushed to hospital 2 days before my flight. Wanted to stay but didn't have the 400k in bank long enough. Immigration gave me an extra 60 days ( visit family) to fill the gap. I then got another yearly extension on the back of that later. You'll need a letter from doctor if your wife can't apply in person with you.
