Your Business+ Unsecured Overdraft is linked to your Business+ Account. You access your overdraft funds the same way you access your own eg. With your Debit Mastercard, in-app transfers, direct debits, BPAY, etc. If you overdraw your Business+ Account, don’t worry, your Business+ Unsecured Overdraft covers you (up to your approved limit) until you get your balance back in the black. You only pay interest on what you have used.
