The school catchment trap: one street can cost you $100k

School catchments are one of the biggest hidden factors in Australian property prices. Two houses on the same street, 200 metres apart, can differ by $100,000 or more. The only difference? One is inside the catchment for a high performing public school. The other is not.

Most buyers find out about this after they have already fallen in love with a property. Some find out after settlement. By then it is too late.

What is a school catchment?

Every public school in Australia has a defined geographic area called a catchment zone. If you live inside that zone, your children have a guaranteed right to enrol. If you live outside, they may be able to attend if there are spare places, but there is no guarantee.

In popular areas, schools are often at capacity. That means living outside the zone usually means your kids go to a different school entirely. For families who chose a suburb specifically for its schools, this can be a dealbreaker.

Why boundaries are tricky

Catchment boundaries do not follow suburb lines. They follow specific streets, and sometimes they run down the middle of a street. One side is in. The other side is out.

Boundaries also change. State education departments review them periodically, especially when new schools open or existing schools reach capacity. A property that was inside a catchment when the previous owner bought it may not be inside the same catchment when you buy it.

Real estate agents are generally not required to disclose catchment zones. Some mention it if it is a selling point. Most do not. It is the buyer's responsibility to check.

The price effect

Research consistently shows that properties inside the catchment of a high performing school sell for more than comparable properties outside. In Sydney, the premium can be 5 to 15 percent depending on the school. For a $1.5M property, that is $75,000 to $225,000.

This works both ways. If you are buying inside a good catchment, you are paying a premium for it, so make sure the school is actually one you want your kids to attend. Check the NAPLAN results, the ICSEA score (which measures the socio-educational advantage of the school community), and visit the school if you can.

If you are buying outside a good catchment but close to the boundary, do not assume you will get in. Contact the school directly and ask about their enrolment policy for out of area students.

How to check

Each state has its own school finder tool. In NSW, it is the School Finder on the Department of Education website. In Victoria, it is findmyschool.vic.gov.au. In Queensland, it is the School Catchment Map on the Department of Education site.

You need to enter the exact street address, not just the suburb. A suburb can have multiple catchments for different schools.

On housematch, we show the school catchment for every listing automatically. We also include the school's NAPLAN performance band and ICSEA score from ACARA data, and the walking distance from the property to the school.

What to look out for

Check the catchment before your first inspection, not after. If the school is a key reason you are looking in that area, confirm the boundary has not changed recently. Look at both primary and secondary catchments as they are often different. And if a listing says "close to great schools," check whether "close to" means "in the catchment of." They are not the same thing.

The data is public. It just takes time to find. That is exactly the kind of thing housematch is built for.
