The agreement, announced Friday, links the gas field operations of Santos and Australia Pacific, both involved in ventures in the Surat and Bowen natural gas basins, through an 86-mile pipeline in Queensland.
The arrangement will "make gas transportation more efficient ... and reduce the need for additional pipeline infrastructure," a statement said.
"It's a win-win for both projects and puts us in a strong position as we work towards the delivery of first liquefied natural gas in 2015," said Trevor Brown, a Santos vice president in charge of Queensland operations.
Neither company offered information about the volume of LNG exports planned from their operations in Australia.
Australia is a premier exporter of LNG. Several Asian countries have secured long-term natural gas supply contracts from companies operating in Australia.
