One of Australia’s primary transport challenges is the achievement of sustainable cities. An important part of meeting this challenge is a growing awareness of the symbiotic relationship between the goals of sustainable cities and children’s rights. The principles of the Convention of the Rights of the Child (CRC) highlight the responsibility of the States Parties to uphold the child's right to live in a safe, clean and healthy environment and to engage in free play, leisure and recreation in the environment. According to the CRC a child’s well-being and quality of life is the ultimate indicator of a healthy environment, good governance and sustainable development (UNICEF, 1997). A key characteristic of a child-friendly city is its capacity to provide opportunities for children to have freedom of movement to explore their environment uninhibited by physical, social or cultural constraints. Using this criterion, Australian cities may not rate highly in terms of their child-friendly status.
