The idea of a $6 billion trans-Australia pipeline linking large gas fields off Western Australia to the east coast has got a new lease of life under the Neville Power-led National COVID-19 Co-ordination Commission, with the aim of reviving gas-based manufacturing despite serious doubts about its economics.

The trans-continental pipeline, which was found to be unviable two years ago and met criticism from WA Energy Minister Bill Johnston on Tuesday, is among options being considered by the commission as it works up recommendations to be put to the Morrison government, according to sources.
