First up, you'll need to create an account on ASIC Connect and request an ASIC Key.
Once you get your ASIC key, you can link your business name to your new ASIC Connect account and update your details. Having direct access means you can edit your details in future too.
Keep in mind that you'll need to pay the registration fee within ten days otherwise your application will be cancelled.
For more information, check out the ASIC website.
