In addition to the 2% cashback deal HSBC are now offering $100 bonus for new accounts after some hoop jumping.
The AUD100 bonus paid in AUD to new HSBC customers (Not held an account in last 6 months) who open an HSBC Everyday Global Account before 31/07/20 and deposit AUD2,000 or more per month for three consecutive months within 6 months of opening the account.
It looks like a poor conversion rate to me. It seems to be about 1.75% difference from the mid-market rate.
I was going to use it to store GBP for an upcoming trip but I'm not going to use it to convert from AUD to GBP. I'll use something like Transferwise to do the conversion and send it back to the account as GBP. Unless someone else has a better suggestion…
