Answer

"Australia has significant quantities of known gas resources."

Western Australia alone has an estimated 443 trillion cubic feet of gas, enough to meet its current domestic and export needs for 113 years.1 

Elsewhere in Australia there is currently enough known economically viable gas reserves to last around 60 years at current production rates.2 

There is enough natural gas in Australia to help take the world well into the future and support renewable and other emerging technologies as we transition to net zero emissions.
