You can transfer money between your own accounts, or between P&N accounts you are a signatory on, by using internet banking or the mobile app.
Go to Transfer/Pay and select the accounts you wish to transfer between and enter the amount you want to transfer. A reference can be added so you can easily identify the transaction on your statement.
If you want to transfer to another P&N account where you are not a signatory, you will need to use Pay someone and use a PayID or the P&N Bank BSB 806-015 and account number.
