“Hyams Beach, New South Wales, has the world’s whitest sand according to the Guinness World Records.”
It’s a claim that has been published repeatedly for decades. The Sydney Morning Herald refers to it as far back as 1987. And now, every few months, a major news publisher (including this one) or someone on social media picks up that tag and runs with it. No questions asked.
The only problem is, it’s not true.
