What Age Do Kids Start School in NSW?
In New South Wales, children can begin Kindergarten at the start of the school year if they turn 5 on or before 31 July. If your child’s birthday falls later in the year, they will begin school the following year.
It is compulsory for all children to be enrolled in school by the time they turn 6. This flexibility allows families to decide whether to start school earlier or wait until their child is a little older, depending on readiness.
This topic is one of the most common questions parents ask, which is why it’s also a frequent Google search query.
Kindergarten Age in NSW
For most families, the key question is: “What age is Kindergarten in NSW?”
Children are usually 4 turning 5 or already 5 years old when they start Kindergarten.
Some parents prefer to wait until their child is closer to 6, especially if they feel their child would benefit from another year of early learning.
All children must be in Kindergarten by the year they turn 6.
This flexibility means you can tailor the school start to your child’s developmental needs while still meeting state enrolment rules.
NSW School Age Cut-Off Dates
Understanding school age cut-off dates is crucial. In NSW, the cut-off date is 31 July:
If your child turns 5 before or on 31 July, they may start Kindergarten that year.
If your child turns 5 after 31 July, they start Kindergarten the following year.
This system is slightly different from other states. For example:
In Victoria, the cut-off date is 30 April.
In Western Australia, the cut-off date is 30 June.
That’s why our calculator is useful for families moving interstate or comparing education systems across Australia.
