*** for transferring a minimum of 800,000.- THB from Australia to your Kasikorn bank account, you can use WISE or REMITTLY
Kasikorn, Siam Bank PLC and Bangkok Bank fortunately are the three banks that are not underlying the limit of 50,000 THB for one transaction. With WISE, the limit sending money to your account is 2 million Thai Baht.
*** for applying to the “change of visa type” to the “90-days Non-Imm-O retirement visa” inside Thailand, you need first to INVALIDATE your existing stay permit.
Normally your most recent stamp becomes invalid when you leave Thailand without a re-entry permit
In case you bought a multi entry permit for your second year, you need to wait until the expiry of your current stay permit, before you can
EITHER
apply for a new visa in Australia,
OR
Enter Thailand on a tourist visa or a visa exempt entry
and immediately visit Immigration and apply for the “change” from a tourist visa to the 90-days Non-Imm-O retirement visa.
You need proof that a minimum of 800,000.- THB are sitting in your Kasikorn account. On some Immigrations you need proof that the money came from abroad (WISE knows how to code your transaction so it will show as a FET foreign transfer into your Kasikorn account)
As soon as 30 days are left on the 90 days from the Non-O visa, and the money has been sitting in your account for a minimum of two months, you can apply for the “1-year Extension of Stay Permit” on Immigration
Following are listed on a .pdf from Immigration, the requirements for doing the change
