So essentially about 5% against the mid-market rate?
To be honest, to get forex in cash in Brisbane city right now, 5% is probably the lowest margin possible at the best exchange places (inclusive of all commissions, where and if applicable). In some cases, even for "common" currencies, that margin is 7% or 9%.
There are not many Asian forex places in Brisbane, so we probably lack that competition right now.
Is that from an Asian forex place?
Again, I'm guessing Brisbane is not exactly brimming with forex competition.
In short, maybe it's back to 28 Degrees (or the Citi card I don't have and can't remember).... at least the margin is only whatever Mastercard charges on the day against the midmarket.
