In late 2014, the AU announced a $3.4bn ($4.0bn) gas pipeline project that would link Papua New Guinea to Papua New Zealand and supply gas to the country.
At the time, the pipeline was touted as a way to increase export capacity and to cut emissions.
But, as the project came under scrutiny, the Australian government pulled the plug on the project, saying it did not meet its commitments and would have been too expensive to run.
The pipeline is now being assessed by the US National Energy Board (NEB), which is assessing the project for the first time.
“We are confident that the project is safe and sound and the NEB has reviewed the project and will make a final decision at the end of the year,” the company’s chief executive, Robert Bewick, said at the time.
But the NEBs final decision is still to be made.
And the final decision could be delayed until at least the end.
Australia’s gas-fired electricity industry has suffered from oversupply in recent years and a number of small outages, including one at a power station in the eastern Kimberley state of South Australia.
