Origin Energy's Australia Pacific LNG project in $2bn blowout ORIGIN Energy's Australia Pacific LNG project at Gladstone is the latest Australian mega-project to experience a cost blowout, with estimated development spending jumping almost $2 billion. Origin, which today also said it was slashing 850 jobs this financial year to cut costs, said a review had increased capital cost estimates of the giant project to $24.7bn, up from $23bn announced when a second stage was approved last June.
