Australia’s big superannuation sector will pitch to US fund managers this week, armed with research showing it already has more than $1 trillion in international investments and is growing so fast it is on track to control the world’s second-largest retirement pool within a decade.

Super fund bosses, business leaders and government officials, including ambassador to the US Kevin Rudd, will gather with American asset managers and other investors and officials at a summit in New York and Washington, which aims to build ties and open up investment opportunities.
