Around Australia a vocal band of activists have joined a worldwide protest movement against the arrival of the next generation in wireless technology known as 5G. Activists claim 5G is an invisible and potentially deadly health hazard, blaming the radiation emitted by the technology for a range of long-term health problems. On Monday Four Corners investigates these claims, exploring how the technology works and examining the scientific studies undertaken into whether the technology is actually a threat to our health. The program investigates the rise of the anti-5G movement and the spread of wild conspiracy theories tying the COVID-19 pandemic to the 5G rollout. Piecing together the viral spread of these theories, the program uncovers a sophisticated misinformation campaign.
