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.

    Politician becomes engineering guru after reading a articles. What could go wrong?
  • " I was wrong ", now there is a comment that you will never hear a politician say.

    "It may affect the contractors reputation" It damn well should affect them, that work is dangerous but worker safety is a must!
  • @philhogan5623
    I can't think of a single infrastructure project that DIDN'T go way over budget. It doesn't help that contractors immediately bump up their prices as soon as they see the words 'government project'.
  • @kirkjohnson6638
    So, it's not a $2 billion mistake, it's a $12 billion mistake and that is if they don't overrun their current projections which is very dubious.
  • Not in my back yard always seems the response to any proposed infrastructure project. But with that said fair compensation should always be on offer.
  • @christophero1969
    This is comparable to watching children playing in a sandbox and discovering the different properties of wet-sand vs. dry-sand. The public is being taken for a ride, in my opinion.
  • @mickking5913
    It seems that florence shouldn't have been used until they were deeper and in the hard rock.The company in charge of the tunnelling should have known this so therefore they should pay all the extra costs not us the taxpayers.
  • @nedenede
    Mismanagement of public funds in the billions. Why isn't a public inquiry called and pple held accountable? The public needs to know.
  • @leskobrandon691
    This has $100 billion written all over it by the time they get this done. Isn't one of the reasons you release the names of companies with safety violations is to affect their reputation? Unbelievable
  • @scottgordon1781
    Oh crap , they tunneled ahead and ignored it :-) They knew it was soft !

    People can’t pick a flower in a national park but these guys can trash it.
  • @dedrakuhn6103
    Skip the video to 22.20 minutes in to begin watching before starting at the beginning of the video. Whoever choose the order of events should have put the quick overview of this project first
  • @annaclarke7643
    There’s small mistakes and then there’s HUGE mistakes that we all pay for. Promising outcomes seems to be the Australian infliction.
  • @captainpoppleton
    We recently all learnt about ocean depth pressure. Next subject is slurry.
  • @actualfacts1055
    The project should have been cancelled after the geology assessment was done.
  • @Anamnesia
    Hold on... Wait a minute... Is this Four Corners or is it UTOPIA ???
