Teachers and schools are constantly trying to figure out the best way to handle challenging behaviour. One of the go-to tools? Suspension. One in five students in NSW has been suspended from school... and new research shows that being excluded not only affects academic performance ... but mental wellbeing as well. So when is suspension the right option? Mark Johnson is Youth Programs Coordinator for south west Sydney YMCA, Angela Falkenberg is the President of the Australian Primary Principals Association, and Professor Kristin Laurens is Program Co-Leader of the Health and Wellbeing Program at Queensland University of Technology's School of Psychology & Counselling.

The ABC has launched a new interactive tool that brings together thousands of years of oral histories that have been passed down for generations. The Deep Time website tells the ancient story of our continent and its people... and explores Aboriginal and Torres Strait Islander culture over 65,000 years. The site covers everything from how people migrated across the land, how they survived an ice age.. and how they lived alongside megafauna. Solua Middleton is co-executive producer of Deep Time and Dr Noel Nannup contributed to the project.
