The document discusses the importance of physical activity and PDHPE (Personal Development, Health and Physical Education) in primary schools. It notes that a 2002 NSW summit found childhood obesity requires complex solutions. It recommends schools dedicate 120 minutes per week to physical activity and develop students' movement skills. The benefits of physical activity for children include healthy growth, weight control, bone/muscle strength, and brain development. However, many Australian children do not meet activity guidelines. Parents are urged to support their children in being physically active.
