Morning Dajana,
Randwick would have normally cancelled the direct debit as soon as the change of address is made by the Real estate agent.
In saying that though we are currently reviewing this whole process and moving forward the real estate agent will be required to provide evidence that they are responsible to pay the rates on the owners behalf.
Council will then write to the owner and advise that the direct debit has been removed from the account, due to the change of address by the real estate agent.
