Looking at the catchment published for 2025 in NSW, it appears that significant zoning changes had happened. Previously there are areas that covered by single sex school only, now it appears that all area are covered by coed schools as well. Just to note, when I went to high school in Sydney decades ago, same practice applied as well, where choice of single sex and coed high school was offered to me.
Efforts are now being made to merge the previous separate boys and girls high school into coed schools as well. The most famous example is probably the now merged Randwick High School.
For this particular article, I will use Ashfield Boys and Girls High School as an example to illustrate what had happened to its school catchment in 2025.

The combined striped area are all part of the Ashfield Boys and Girls High School catchment, this was not changed from 2024 to 2025.
The yellow striped area marked as “1” is also part of the Concord High School catchment in 2025 now.
The green striped area marked as “2” is now part of the Strathfield South High School catchment for 2025 as well.
The purple marked area marked as “3” is now part of the Dulwich High School of Visual Arts and Design catchment as well.

When discussed from the perspective of a particular school is often referred to as one of the following terms.
