The practitioner must not supply, administer, promote, advertise, or recommend the use of, any medicinal substance to any person or patient, directly or indirectly, in the course of a business or other commercial or private activity (whether paid or unpaid), unless the substance is approved by the Therapeutic Goods Administration (TGA) (i.e. substances labelled AUST-R or AUST-L and listed on the TGA’s Australian Register of Therapeutic Goods).

To remove any doubt, a medicinal substance is any substance that is intended to achieve, or is likely to achieve, a therapeutic action by pharmacological, chemical, immunological or metabolic means in the body of a human person, and excludes food items.
