Inside the engineering megaproject that went horribly wrong | Four Corners

Australia’s Snowy 2.0 was sold as a nation-building megaproject for a low-carbon future – and was meant to be feeding power into the grid by the end of 2024.

Instead, the pumped hydro project, which was once estimated to cost $2 billion, is four years behind schedule and now forecast to hit $12 billion.

In this documentary, Four Corners reveals the inside story of Snowy 2.0 and how it all went so horribly wrong.

Reporter Angus Grigg challenges its founding champion, former prime minister Malcolm Turnbull, who says as much as $2 billion of the cost blow out can be traced back to a massive tunnel boring machine called Florence.

Florence is currently stuck.

This episode was originally broadcast as ‘Tunnel Vision’ on 23 October 2023 on ABC TV and ABC iview.

Four Corners is Australia’s premier investigations documentary series.
