New figures show Santos GLNG has provided more than $11.6 billion worth of work to Australian businesses since January 2011, with $6.2 billion spent in Queensland alone.
Regional communities have been big winners, with over $492 million spent collectively in the Maranoa, Western Downs and Toowoomba regions, and over $267 million in Gladstone and Rockhampton.
Santos' Vice President Queensland Trevor Brown said the figures showed just how significant the economic benefits of Santos GLNG were to local, state and national economies.
"As a proudly Australian owned and operated company, we are very pleased to share the benefits of our world-class natural gas operations with the communities in which we operate," Mr Brown said.
"Santos GLNG is delivering for the people of Queensland by using local businesses for work including drilling, engineering, equipment fabrication, camps, transport, trades, and environmental services.
"We're building a new industry for Queensland that will drive the state economy over the long term, which means our contribution won't stop here.
"As well as creating opportunities for local businesses, we will contribute billions of dollars in taxes and royalties over many years – money that can go to Queensland's schools, hospitals and roads."
"We've also invested over $50 million on community infrastructure, organisations and events, including roads, airports, hospitals, schools, the environment and the arts."
The figures represent money spent during the period from January 2011 to December 2013, and were published in a progress report of Santos GLNG's Social Impact Management Plan.
Santos GLNG is a pioneering joint venture between Santos, PETRONAS, Total and KOGAS to supply liquefied natural gas to global markets.
