my salary goes in. So I use it like a normal debit card. Then when need to transfer money in thailand and internationally use the app. Makes it very easy.
form is on their website. Just search Australia embassy CNI or marriage in thailand. Print and fill in form. Copy of your passport. Partners ID card and then post to the embassy. Phuket may do inperson but with covid restrictions the time I applied 2 months ago they were not doing in person.
I had a friend who has 2 residences. 1 in phuket 1 udon Thani. His previous 90 report was in Udon but came to phuket for 2 months work. His next 90 day came due and he put Phuket address. They rejected his report as didnt match immigrations records.
In short keep reporting already registered address unless you move permanently or feel like going to immigration every 3 months.
