Where can I find out about how many Aboriginal and Torres Strait Islander members of parliament there are and their names?
You can find this information in the Parliamentary Handbook. The Handbook has a list and timeline showing members of parliament who identify as Aboriginal and/or Torres Strait Islander. You can see it here.
The Parliamentary Handbook is published by the Parliamentary Library. It includes information on the service and biographical details of all current and former senators and members of the House of Representatives.
