Given the recent large scale development in Chatswood, it is not a surprise that a new public school will be build in the area. One important thing to note is that in 2022 significant part of existing Chatswood Public School’s catchment will be handed to Lindfield Learning Village and Roseville Public School.
Currently, it is speculated that the new public school will be sited at dive site for Sydney Metro located at the corner of Pacific high way and Mowbray road. You can look at the 2021 catchment map and see the proposed site marked by X.
Looking at the site, this likely means further reduction of the catchment of the existing Chatswood Public School catchment, possibly extend to Mowbray, Artarmon, and nearby Willoughby Public School as well. These three schools all received recent upgrades, so they are probably not under immediate heavy enrolment pressure. I would guess most of the catchment of this new school will come from the existing Chatswood Public School’s catchment.
However, this will imply very significant changes to the catchment when the new school is established. Given the current timeline, it will be a few more years at least.
