It also marks the completion of Queensland Curtis LNG – the first of three Queensland CSG-to-LNG export projects to be commissioned.

LNG is natural gas (methane) that has been chilled to -161°C so that it becomes liquid. Once it has been liquefied, it occupies about 1/600 of the space it fills in its gaseous form, meaning it can be transported across the world in purpose-built tankers.

Australia’s enormous natural gas reserves and Asia’s demand for clean and reliable energy have seen an unprecedented level of investment in Australian projects in recent years.

Queensland Curtis LNG is now Australia’s fourth operating LNG project. Another six projects – representing a total investment of more than $180 billion – are still under development.

In 2012-13, Australia shipped 23.9 million tonnes of LNG cargoes, earning $13.7 billion in export revenue. Australian LNG exports are expected to almost quadruple over the next few years. By 2018, Australia is forecast to overtake Qatar as the world’s number-one producer of LNG.

APPEA Chief Executive David Byers said: “The first Queensland LNG cargo represents an historic milestone, not only for the state of Queensland, but for all the people who have worked so hard throughout the past five years to make this enormous project a reality. Successive state and federal governments, local councils, agricultural bodies and community representatives have shown leadership to realise the emergence of this multi-billion dollar industry.

“Thousands of jobs have been created, regional communities have been renewed, and a long term stream of royalties will flow to the State, which will benefit all Queenslanders.”

The Queensland Government forecasts that in 2015-16 LNG production will underpin a surge in exports to boost economic growth by 5.75%.

Mr Byers said: “Extraordinary technology and the emergence of a burgeoning Asian market have allowed industry to produce and commercialise Queensland’s enormous gas reserves.

“And because natural gas is a much cleaner-burning fuel than traditional energy sources, exporting gas to places such as China and India is among the most meaningful contributions Australia can make to reducing global greenhouse emissions.”
