Commonwealth Superannuation Scheme (CSS)
The CSS closed to new members from 1 July 1990. The only exception applies to previous members who, in specific circumstances, are able to return to the scheme. The CSS is a hybrid scheme including both a defined benefit and an accumulation benefit.
CSS members can make basic contributions equal to 5% of their superannuation salary or can elect to make no contributions. Optional supplementary contributions are also allowed. Employee contributions are paid into an investment fund (the CSS Fund). This investment fund is managed by Commonwealth Superannuation Corporation  (formerly the Australian Reward Investment Alliance).
As a CSS member, your main benefit will generally be paid as a pension. The amount of that pension is determined by your reason for leaving the scheme, the time that you have contributed to the scheme and your age on leaving the scheme. In some cases your final salary will also be a factor in determining your pension.
