I rang HSBC's international department on Monday and they took our application over the phone for a UK bank account. The pre-filled application form was then emailed to us. Now we print the form, sign it, and take it to a HSBC branch with our identification and to pay the application fee of $200. We will also need to open an Australian HSBC account at that time and we'll be able to transfer from our Australian account to the UK one.
Once the accounts are opened, I don't see why we can't just use Ozforex to transfer to the UK account.
During the conversation with HSBC I discovered a major difference between Australia and England's banking. We can have a Visa or Mastercard as a debit card on an ordinary transaction account in Australia. HSBC said you can only have a card for use at an automatic teller machine on an ordinary account. If you want a Visa or Mastercard it has to be a credit card. This used to be the case many years ago in Australia. So, we also applied for a credit card account in the UK as well.
It's all been easy so far. The cards will be sent here to us in Australia in the next month or so. We will have to go to Melbourne to take the paperwork to a branch. There isn't a huge number of HSBC branches in our state and all of them are in Melbourne. We have another item on our list almost ticked off!
