Our Locations

Mainstream Group Holdings Limited is a leading listed fund administrator with offices around the world so it is easy to meet with us or get in touch.

Mainstream’s directors opened our first office in Sydney, Australia, in 2006 after successful management consulting careers in outsourcing and shared services.

Our Melbourne, Australia, office opened soon after in 2007, followed by Singapore in 2012 and Hong Kong in 2013. In 2016 we acquired New York based Fundadministration, Inc and Galileo Fund Services Limited and opened our Malta office.

Today we administer over AUD $123 billion in funds and employ more than 217 people.
