This information is related to NSW state schools. As we know Term dates in NSW are divided into two division : Eastern Division and Western Division. Except for the date of Term 1 all other dates of the remaining terms are same for both Eastern and Western division.
Although Catholic schools and Independent schools have their term dates set according to the state school dates but it should be confirmed as it may vary from school to school. Do check with the schools to confirm the term dates.
*Term 4 finishing dates for Year 12 are different as year 12 only have term 3 and pass out in the month of late September or early October. There is a short break before the final exam / HSC. Dates will be updated once they are available to us.
