If you need to update your parent organisation details that must be done on a separate form provided by the government.

“Use this form to notify the department of changes to the legal entity including the name, location and contact details for the entity. (The legal entity is the Organisation (sole trader, partnership, company or trust) that is the Approved Operator for CCB purposes).”
