I have a brother in Australia. I needed to transfer him some money. So I got all the necessary details from him, wrote them down and included the amount to transfer on a sheet of paper. I handed it to the clerk and the conversation went like this:

Me: I'd like to transfer some money to my brother in Australia
Clerk: OK. Is that the IBAN number?
Me: No, its the SWIFT number. Australia uses SWIFT. IBAN is Europe only
Clerk: Is the money going to Australia?
Me: Yes, its going to Australia
Clerk: OK, I've input everything except the BSB number
Me: That needs to go on. It stands for Bank, State, Branch. Its like our 'Sort' code.
Clerk: I'm looking at my IBAN instruction screen and it doesnt mention it
Me: It isnt an IBAN transaction. Its going to Australia. They use SWIFT. It wont get there without the BSB code..
Dont you have a box on the screen that says 'receiving bank code'? If not you better ring your international department.
Clerk spins screen so I can see it
Me: Can we put it in the box that says 'receiving bank code' please?
Clerk: Will just ask my colleague... yes we can put it in there.
Clerk: It wont let me key in letters
Me: How do you mean? Its all numbers?
Clerk: It wont let me key in the letters BSB
Me: Would it let you key in the letters 'SORT' if it were a UK bank?
Clerk: No
Me: Thats probably it then. Try it without the letters BSB
Clerk: Oh thats worked fine. Is the amount written here the amount you wish to transfer
Me: Yes thats the amount I would like to transfer
Clerk: Its gone through now!
Me: Oh good
Clerk: Can I help you with anything else today?
Me: Er.. no thanks
My bank wont let me transfer money outside the UK. Maybe they think I dont know what I am doing?
