When you took the loan out, BankSA registered a mortgage over your property. That registration stays until you tell them to remove it. The discharge authority is how you tell them.
You need one in three situations: you’re selling, you’re moving the loan to another lender, or you’ve paid the loan off and want the mortgage lifted. It’s the same form each time — you just tick a different reason.
BankSA's PDF isn't called a discharge authority — it's the ‘Request to Amend an Existing Security’ and covers full and partial discharges. There is also an online Property and Security Request form that can't be saved partway. They state the fee — $350 per loan account — and say to expect a confirmation letter about 10 days after they receive the form.
Most pages treat these as one process. They aren’t, and the difference decides who does the chasing.
If you’re selling
If you’re refinancing
BankSA publishes a discharge fee of $350, which puts them in a small minority — most lenders don’t state a figure. It is added to your final payout rather than billed separately.
Two other costs catch people out. The state land titles office charges a registration fee, which your conveyancer passes on. And if you’re still inside a fixed term, break costs are separate from the discharge fee and can run into thousands. Ask for both figures before you commit to a settlement date.
BankSA is part of the Westpac Group. The process is similar across the group, but each brand has its own form and its own discharge team — use the one for the name on your loan.
BankSA doesn't publish a processing time. The other big lenders ask for at least 10 business days, so plan on that as a floor and allow three weeks end to end. Call 1300 304 660 if you have a settlement date locked in.
Yes. BankSA publishes a discharge fee of $350, and it's added to your final payout figure rather than billed separately. That makes them one of the few — most lenders don't publish a number at all. Break costs on a fixed rate are separate and can be much larger.
It's the form that tells BankSA to release its mortgage over your property. You need one whether you're selling, refinancing to another lender, or paying the loan off entirely. BankSA calls theirs the Request to Amend an Existing Security (or the online Property and Security Request form).
