In 2026, the most influential voices on health in Australia are almost never doctors. They are chefs, naturopaths, podcasters, and former personal trainers. They sell supplements, light-therapy devices, fasting protocols, and theories about the immune system that would not survive a first-year medical exam. Their audiences are large, loyal, and growing. Their content is unconstrained by Section 133 of the Health Practitioner Regulation National Law, because Section 133 does not apply to them.
It applies, instead, to the people best qualified to correct them.
This is the architecture of the misinformation economy that has built itself around Australian healthcare over the last decade. The regulatory logic that quietly enabled it deserves a closer look.
The original logic
Section 133, and the AHPRA advertising guidelines that operationalise it, were drafted in good faith to protect patients from misleading claims by registered health practitioners. The drafters had a specific historical problem in mind: the cosmetic-surgery clinics making lavish promises in glossy magazines, the chiropractor advertising cures for asthma, the dentist whose website carried before-and-afters that omitted the unhappy ones.
The rules that resulted prohibit testimonials about clinical services, superlative language, comparative claims, the word "specialist" by anyone not entitled to use it, and any creation of an unreasonable expectation of benefit. The maximum penalty is sixty thousand dollars per offence. For a profession whose membership is conservative by training and risk-averse by liability, these rules have done what they were designed to do. They have made registered practitioners cautious about anything they say in public.
What the drafters did not anticipate is that, by the second decade of the twenty-first century, there would be an entire parallel media economy of health communicators to whom these rules do not apply at all.
The parallel economy
The last ten years have produced a recognisable taxonomy of unqualified health figures whose reach now dwarfs that of any professional body. The celebrity chef who pivoted from cooking shows to selling a five-figure light-therapy device as a COVID-19 intervention. The young wellness blogger who fabricated a terminal cancer diagnosis and built a million-dollar cookbook empire on the claim that diet had cured her. The naturopath banned by a state health department from giving health advice in person, whose online seminars continue to draw audiences in the tens of thousands. The fitness identity with theories about seed oils. The podcaster who interviews them all and adds nothing but a microphone.
These figures share a useful set of characteristics. They have no AHPRA registration, so AHPRA cannot discipline them. They belong to no professional college, so no college can sanction them. They make the kinds of claims that would end a doctor's career inside a week, and the absence of a regulatory framework means the only consequence they face is whatever the platform's content moderation team decides to do, which is usually nothing.
Meanwhile, the GP who would like to write a measured social-media post explaining why the activated-almond claim is nonsense is faced with an awkward calculation. Section 133 prohibits her from making comparative claims. The guidelines warn against any post that could be read as creating an unreasonable expectation of benefit. Her medical defence organisation will tell her, accurately, that engaging publicly with misinformation is a low-reward, high-risk activity. So she does not engage. The misinformation goes unanswered. The vacuum widens.
What the asymmetry costs
It would be easy to treat this as an abstract problem of information ecology. It is not. It is a clinical problem with measurable consequences.
Childhood immunisation rates in some Australian postcodes have drifted below the herd-immunity thresholds public health authorities planned around in the 2010s. Cancer patients arrive at oncology clinics having spent months on bicarbonate-soda regimens prescribed by people on encrypted messaging apps. Parents of newborns ask paediatricians earnestly about the safety of vaccines that have been administered to billions of children, because the algorithm has fed them weeks of confident-sounding video suggesting otherwise. Endocrinologists report seeing self-induced electrolyte imbalances from extended fasting protocols promoted by figures with no clinical training and no accountability when something goes wrong.
The doctors who could have addressed any of this in advance, in the same forums where the misinformation circulates, are absent. They are absent because the regulatory framework they operate under was written for a world in which they were the only people speaking publicly about health, and the framework was designed to constrain them.
The argument is not that AHPRA should loosen the rules
This is the place where it is tempting to call for deregulation, and I am not going to. The advertising guidelines protect patients from a real and recurring harm. The history of unrestricted medical advertising in other jurisdictions is not an advertisement for the alternative. The framework was built to address a real problem and it continues to address it.
The argument is narrower. It is that the framework was written without an awareness that its operation would create a vacuum, and that the vacuum has now been filled by actors immeasurably worse than the worst-behaved doctor the framework was originally designed to constrain.
Two things follow.
The first is that there is room for AHPRA, the colleges, and the medical defence organisations to actively encourage compliant educational content from registered practitioners, rather than treating any public communication by a doctor as a presumptive risk. Some of this is already happening, slowly. It needs to happen faster, and it needs to be visible enough that the average clinician understands that public writing about their field is not just permitted but quietly encouraged.
The second is that the profession itself has to change its cultural posture toward public writing. The piece I published earlier this month on the discomfort doctors feel around self-promotion described one half of the problem. This is the other half. The discomfort is not only a personal feeling. It is a public health issue. Every credentialed clinician who declines to write publicly about their field cedes that ground to someone who will write about it without credentials, without restraint, and without consequence.
What is actually available
The useful news is that AHPRA-compliant educational content is permitted, and the bar for producing it is lower than most clinicians believe. An article explaining what a condition is, what causes it, what the evidence-based approaches to managing it are, and what the realistic outcomes look like, complies with the guidelines on its face. It contains no testimonial. It makes no comparative claim. It creates no unreasonable expectation of benefit. It is the same kind of writing the practitioner would already produce for a journal or a college presentation, adapted for a non-specialist audience.
This is the work Narrative Digital exists to support. The doctors we work with are not loud, not self-aggrandising, and not interested in becoming influencers. They are increasingly interested in the fact that the silence has a cost, and that the cost is being paid by their patients.
Closing
The rules were written in a room in which it was assumed that the only people speaking publicly about health would be registered practitioners. That assumption no longer holds. The rules constrain the people who would speak responsibly. They have no purchase on the people who will not.
The remedy is not less regulation. The remedy is more credentialed voices, writing carefully and consistently, in the places where the misinformation now lives. The vacuum will be filled either way. The only choice is by whom.
