did you apply for a longterm 1year visa or a 90 day visa? OA is a 1 year visa. Requiring all those things. The non-o 90 day is not consider akngterm visa and you will extend 1year at a time in country.
NO the TDAC is not a screening process at all, It is only a digital arrival card. It replaces the old Tm6 form we had to fill out on landing. The ETA (which is proposed but delayed until further notice) An Electronic Travel Authorization (ETA) is an entry requirement for foreign nationals traveling to certain countries by air. It is digitally linked to the traveler’s passport and used to screen travelers before they arrive.
Just to throw a bit of an idea that you would need to confirm.
The embassy in Canberra, Australia may still offer a non-o dependant visa, alongside the 90 day non-o. Based on retirement.
This was just a few months ago.
