Truth‐telling in the Australian Curriculum
The Curriculum Journal, EarlyView.Abstract Unlike Canada and South Africa, Australia has not completed a national Truth‐telling of First Nations histories. As a consequence, the curriculum is at risk of excluding Truth‐telling, leading to indoctrination of past injustices as part of school learning.
