You can’t have a WP with a DTV obvs, but it’s not really the permit. It’s the visa type - OA - which has several types including retirement visa. I know a visa agent and wealth consultant here and the DTV is deemed the same as a TR in terms of getting a bank account - ie you’ll struggle to get one.
Find the right agent and you’ll be able to get one I’m sure.
Not sure how you expect them to put it in your passport if you've applied online and not given it to them, but I'd take it as a positive - one less page taken up in your passport!
I got my OA there this year and the staff were fine. Few issues on my side, so I had to go a few times, but they spoke English well. This review just seems like one person’s experience as met a handful of others there who didn’t have these kind of issues.
Also, it was rarely busy so never had to wait, even though I had to book an appointment. They just said turn up whenever.
