Fast food outlets are major contributors to unhealthy eating in Australia, but are exempt from national food labelling requirements. There is a need for consistent national requirements for fast food outlets and vending machines to display nutrition information. This should consist of multiple traffic light signposts to indicate levels of key nutrients in products, or at a minimum, kilojoule content information (with a statement about recommended kilojoule intake). Fast food outlets should be required to display nutrition information about each product on menus, menu boards and drive-through boards at the point of sale, and on tags next to self-service cabinets and food displays. Vending machine operators should also be required to display nutrition information about products on the outside of vending machines.
