For the Aussies in this group...
Since your superannuation was 1) taxed when the money was deposited, and 2) the withdrawals are tax free (at least in Australia)
Are transfers from your superannuation into your bank account 1) tax free due to reciprocal tax agreements with Australia, or 2) taxed since they consider the *withdrawal* as having been non-taxed?
Alternatively, if the transfer went from superannuation -> Wise -> convert AUD to THB -> transfer to Thai bank account, would this audit trail suffice to support your answer to the above question?
Finally, can you recommend a good accountant in Bangkok that would be familiar with this issue?
