The US$1 billion will help facilitate the employment of over 3,500 workers over a five-year construction period and create thousands of jobs in the area of natural gas production once the LNG loading facility is completed. 

This will result in an annual economic benefit of around US$6 billion for the US economy. 

IFM Investors chief executive Brett Himbury said the investment will deliver significant returns to millions of Australian superannuation and US pension fund members. 

Mr Himbury said he is proud IFM Investors, an Australian-owned infrastructure investor, is playing a leading role in the provision of private capital to the critical infrastructure needs of the US economy. 

He said that five of the top 10 US public pension funds have also invested in the project. 

Minister for trade and investment Andrew Robb said the investment was a good example of Australian superannuation money contributing to the construction of vital infrastructure and the real economy. 

"The partnership between IFM Investors and Freeport LNG is a prime example of the mutually beneficial business relationships that have developed between US and Australian companies, which will in this instance result in substantial investment and international trade outcomes,” said Mr Robb.

“Our business delegations are all about fostering business relationships that lead to this type of major investment, investments that go both ways, creating more jobs in both countries.”
