The Australian Curriculum and Studies Authority has three new Innovative and Dynamic Educational Activities for Schools (IDEAS) resources:

Acknowledgement of Country: Teachers can use this activity to help students develop an understanding of and respect for Indigenous protocols and culture.Students can also devise their own ‘Acknowledgement of Country’ for use in their class/school.

Developing cultural sensitivity in the classroom: This resource focuses on developing cultural sensitivity and intercultural understanding.

A nation of many cultures: This resource encourages students to develop multicultural understanding, partly through a role play focussing on the treatment of Italians in Australia during the Second World War.
