Renewing a business name can be done directly with ASIC via your ASIC Connect account. If you don’t have an ASIC Connect account you are able to create one at https://asic.gov.au/ by clicking on the blue “ASIC Connect” button.
You must have already received your business name renewal notice in order to renew the business name. Via ASIC Connect you are able to renew the name for either a one or three year period, pay for the renewal and request an invoice.
You can find more information about renewing a business name on the ASIC website
