an Australian pension is not transferable to another person, every person who receives a pension in Australia must apply in person. You also cannot will you pension to another person, not even you wife.
any Australian pension is not transferable to another person. Each person must apply for a pension in Australia in person and follow the qualifications to apply for that pension. You can’t just transfer it to your wife, this is for Australian citizens, I have no idea how other countries do it, but the OP is asking about Australian pensions.
that is correct, the widows pension is a old benefit, and you cannot will your pension to another person, that person must apply for a pension on their own right, and follow the qualifications for the applicable pension.
Unfortunately the answer is no, the widow’s pension doesn’t exsist anymore and if she isn’t at least a Permanent resident of Australia she can’t receive any pension at all. All pension’s are means tested and have a qualification period even the aged pension.
TM30 does not show an expiration date, but your local immigration office may require you to do a new one when returning from a trip inside of Thailand. Always best to check on your local requirements.
You are correct about getting 60 days entry in Thailand as an Australian passport holder, but it is called visa exempt, visa on arrival is totally different altogether, just to correct your terminology.
