Industry super fund REST has entered into an agreement with Cintra Infraestructuras for investing in Australian infrastructure projects.
The two parties are particularly targeting Australian toll-road projects, the super fund said.
"We see this venture as a means of potentially providing better returns to members through an integrated approach to transport infrastructure investments," REST chief executive Damian Hill said.
"Infrastructure is a key asset class for our members as it has the potential to provide growth and security," he said.
"This collaborative approach will facilitate REST and Cintra as long-term investors leading bids for toll-road assets."
The agreement, which includes both investment and operation of infrastructure assets, has no set timeframe, but Cintra chief executive Enrique Diaz-Rato said the company would take a long-term approach to the agreement.
"Australia is a safe and secure place for our company to grow its operations and we will be taking a very long-term approach to our investments," he said.
"REST is a perfect fit for us as they are a very established local investment partner," Diaz-Rato said.
REST has more than $20 billion in funds under management, while Cintra manages a portfolio of 22 road concessions and total managed investments of $27 billion in Canada, the United States, and Europe.
