Local Government Super is local government's own not-for-profit superannuation fund. It is the preferred and designated superannuation fund for employees in Awards and Enterprise Agreements in the industry in New South Wales and was established in July 1997 as a joint initiative of the local government unions and the Local Government and Shires Association.
The Fund has equal representation of employers and employees in the industry. There are two employee representatives nominated by the United Services Union, one by the LGEA  and one by depa.
LGS has a proud history of responsible and sustainable investment (their site has lots of info about this) to complement its good returns.
