Go online and get a Wise account. Not sure about how much you want to transfer or their limits, but I’ve found them the easiest to transfer to and from Australia. Less fees.
I think your daughter needs to be included on the family book in Thailand. You have to be in Thailand to do this. The embassy in London should be able to confirm the requirements. Emails are usually quicker.
Apply for the visa at a Thai embassy or consulate in Australia. They will give you all the information you need to make the application as seamless as possible. My advice would be to shop around and get medical insurance in Thailand. Extremely risky not to have it. If something sudden happens and you can’t get air lifted back to Australia, it can be ridiculously expensive. Something as simple as a mosquito bite or a car accident can have dire consequences. Good luck.
