I can be slow so can someone plse explain Australia's energy policy when it is viable to import LNG when by memory we are nearly if not the largest global LNG exporter.

I haven't checked this for a while but Australia produces about 87 million metric tons of Liquified Natural Gas per year and exports about 80 million metric tons.
Our country requires more than the available balance after exports so we import our extra requirement.
The high exports are a result of contractual arrangements made a long time back.
The Government may intervene to reduce the exports.
Increasing our imports may not be viable as LNG may become quite hard to get and, because importing LNG demands a structural pre-requisite, upping our imports may be difficult until such extra structuring is complete.
There'll be smarter people around on this subject than me but that's sorta where it all stands.
