In all my years of journalism, there is one story that's stuck with me. Twenty years ago I was out bush chatting to diamond explorers about a heist that happened in the remote Kimberley region of Western Australia. I couldn't believe it when some of these diamonds recently turned up in my hometown of Perth. Buckle in because it seems everyone wants to know more about what really went on, even those that had a front-row seat.

It's a heist of grand proportions, and a story straight out of a Hollywood blockbuster. Millions of dollars of diamonds smuggled out of the remote Kimberley, in Western Australia then around the world. But the diamonds weren't lost to the eighties when this heist happened, the stolen gems are back in circulation. On Pink Diamond Heist: how did no-one notice diamonds were being smuggled out of the world's most secure mine? Who were the culprits behind this multi-million dollar heist? And where are the stolen diamonds now?
