A transition to retirement income stream (TRIS) is a specific kind of pension, similar to an account-based pension from where lump sum payments can only be made in limited circumstances.

Members who have reached their preservation age are able to access their superannuation benefits through a transition to retirement income stream without having to retire or leave their job. The amount of pension paid must be a minimum amount in each financial year and is limited to a maximum of 10% of the member’s pension account balance (at the start of each financial year).
