Hi AudioGuy and welcome. With that username, have you looked into Audinate (AD8), not a recommendation, just resonates with your username!
I use Commsec and by default, when I set up the account, which was years ago, it was set so that they as the broker pass on the banking details for depositing dividend payments to the share registry automatically when I buy a new holding. I still have to record my tax file number for each new holding manually by logging into the relevant share registry (computershare, link market services, automic, the boardroom, etc). This is a pain because you have to do it each time you buy a new holding. If you don't then you can end up with withholding tax deducted from your dividends which you would then need to claim in your tax return.
