The National Quality Framework's Quality Area 3 focuses on sustainability, ensuring children are provided with a safe and suitable physical environment. This includes two standards: standard 3.1 for the design of service facilities and standard 3.2 for the use of these facilities. The framework also encourages environmental sustainability by introducing programs that promote waste disposal and recycling, which can enhance locomotor skills, body management, and child development. Additionally, play sessions can be used to develop problem-solving and social skills among children through activities like art, craft, and gardening.
