At the peak of the LNG construction boom, oil and gas company Santos was spending about $10,000 a minute over seven years to bring its $25 billion Queensland-based Gladstone LNG project online.

But the days of new gas mega-projects being built is over as the industry shifts into a new gear of producing gas, says Deloitte.

In a new report, Deloitte says the completion of another two major LNG projects – Inpex’s Ichthys project in the Northern Territory and Chevron’s Wheatstone project in WA – has all but capped Australia’s LNG construction boom.
