If your complaint is not a mandatory notification within the meaning of the National law, it can be made directly to the Commission via this portal.
For registered health practitioners, employers, or education providers you will need to consider whether you have a legal obligation to make a mandatory notification, in accordance with Division 2 of the Health Practitioner Regulation National Law (NSW).
Mandatory notifications must be made to the National Agency (AHPRA). Upon receiving the notification AHPRA would then refer that notification to the HCCC and/or the relevant Professional Council for management as a complaint. Making a complaint to the Commission only, does not satisfy mandatory reporting requirements.
You may also wish to make a complaint to the Commission in addition to notifying AHPRA.
