Ok...Wife's entry and exit understood.
For my part, I went to the Thai Consulate web site in Canberra Australia and only listing I could find for OA Visa was under O-X which is a 5 year based visa.
Seems most of the older type visas are not around anymore.
I was in Thailand back in 2013 for 6 months on an OA visa with 2 entries but doesn't seem to exist now.
I'll check the Sydney web site as it might be different.
With what I could find on the Canberra Consulate web site, I was thinking of foregoing the visa exempt entry and just go straight to a 60 day (TR) tourist visa.
As a side note, wife needs to renew or rather get a new Thai passport as her old one has expired.
Brisbane Consulate is now closed for good and travelling to either Sydney or Canberra is rather extreme, especially with Covid around.
Even with Brisbane it is a 4 hour train trip each way.
There were, around 12 months ago, a team of Consulate personell visiting Brisbane so peolple like my wife could get a new passport but it was never published on the Consulate sites.
Rather, one had to look in Facebook of all places to book any appointment etc.
Does anyone know if this still applies.
Facebook to me is a real PIA....just tried to sign in after a while away and it wanted photo id and who knows what else just to get in the front door of the web site.
