The latest data from the Australian Early Development Index (AEDI) showed the country' s five-year-old children were developing better compared with the results in 2009.
This was said by Australia's Minster for Early Childhood Peter Garrett.
Releasing the results during a community event in Sydney, Garrett said Australian children were showing development improvement in social competence, emotional maturity, language and cognitive skills, and communication and general knowledge skills.
"Research shows that investing time, effort and resources in children's early years, when their brains are developing rapidly, benefits them and the whole community," he said in a statement.
"The overall national improvement means that over the next five years as they hit school age, we can expect 24,000 more children to start their school life better prepared."
