False and misleading health information is not a new problem, but the Internet and social media platforms have amplified the reach of this information. This can have negative implications for the uptake of vital public health interventions (such as large-scale vaccination programmes) and individual treatment choices. Many countries are examining ways to regulate misinformation without disrupting individual rights to free speech. This presentation will look at some international and domestic law reform proposals, as well as the Victorian Health Complaints framework which now explicitly prohibits false claims about cancer treatments and cures.
