I just had a look at my old levy invoice. (We no longer use a strata manager.)
At the bottom, there is a notice about DEFT and authorising the bank to direct debit an account. The wording is as you indicated.
Below the DEFT notice, I see a BPay biller number and code. Is there anything like that on your invoice? If you can see a BPay biller number and code, you can set up payments from your internet banking portal and ignore that DEFT payments paragraph. I never authorised Macquarie Bank to take money from my account.
