How school catchments and enrolment work in Australia
Public schools in Australia operate on a "catchment area" or "intake zone" system. Each school is assigned a specific geographic area, and children who live within that area are guaranteed enrolment. Children outside the catchment can apply but enrolment is at the principal's discretion and usually only available if there are spare places after catchment students. This is why where you rent or buy can determine where your kids go to school - sometimes for 13 years.
Catchment boundaries follow specific streets, not suburbs. It is common for one side of a street to be in a high-performing school's catchment while the other side is zoned to a different (sometimes lower-performing) school. Always check the catchment for the exact address before signing a lease, especially in cities like Sydney and Melbourne where boundaries can be unintuitive.
Where to find official catchment maps
- NSW: NSW Department of Education school finder
- Victoria: Find My School (official tool)
- Queensland: EdMap (catchment search by address)
- Western Australia: Schools Online (WA Dept of Education)
- South Australia: SA Education school finder
- Tasmania: Tasmanian Department for Education
- ACT and NT: each Department of Education publishes catchment maps
School performance: how to interpret the data
The most reliable independent data source for Australian schools is the federal government's My School website. Every school - public, Catholic, and independent - publishes:
- NAPLAN results in reading, writing, language conventions, and numeracy for Years 3, 5, 7, and 9
- ICSEA (Index of Community Socio-Educational Advantage) - a score that adjusts performance for the school's demographic context
- Year 12 outcomes for secondary schools (Year 12 attainment and post-school destinations)
- Attendance rates and enrolment numbers
- Total funding from government plus fees
The key insight: look at NAPLAN performance relative to ICSEA, not in absolute terms. A school that scores slightly below the national average but well above its ICSEA prediction is actually outperforming. A school that scores above average but below its ICSEA prediction is underperforming relative to its demographic.
Selective and specialist schools
Outside the catchment system, every state runs selective schools and specialist schools. These select students by competitive exam, audition, or aptitude test rather than residence. Notable examples:
- NSW: 47 selective public schools including James Ruse, Sydney Girls, North Sydney Girls/Boys, Penrith High - entry by the Selective High School Placement Test in Year 6
- Victoria: Select Entry High Schools (Mac.Rob, Melbourne High, Suzanne Cory, Nossal) - entry by exam in Year 8
- Queensland: Queensland Academies for Year 10-12 high achievers, plus state high schools with specialist programs (music, sport, languages)
- WA, SA, ACT: Gifted and talented programs in select public schools, entry by test
Frequently asked questions
I just arrived - how quickly can I enrol my child?
Public schools must enrol any child living in their catchment within a few weeks of the application. You typically need: passport, visa grant letter, proof of address (rental agreement is usually sufficient), and previous school records (translated if not in English). Some schools require an "intake assessment" for new arrivals to determine year-level placement and language support needs.
What if my child does not speak English?
Every state has an English as an Additional Language program (EAL or EAL/D) for newly arrived students. NSW and VIC have intensive English language schools and centres where children spend 6-18 months learning English before transitioning to mainstream schools. Other states embed language support within mainstream schools. None of this costs anything for public school students.
Can I get my child into a school outside our catchment?
It depends on the school. Popular schools fill up with catchment students alone and rarely accept out-of-catchment students. Smaller schools or those with surplus places will consider out-of-catchment applications. Apply early (often 6-12 months before the start of the school year), explain your specific reasons, and accept that the answer is often no.
How are class sizes determined?
Government primary school class sizes are typically capped at 26-30 students depending on state and year level. Public secondary schools are usually 24-30 per class. Catholic and independent schools vary - some elite independents advertise 18-22 per class as a selling point, but many Catholic systemic schools have similar sizes to public schools.
Do I need to apply by a specific date?
For Year 7 entry to selective schools and elite independents, applications often close 12-18 months before entry. For standard public schools and Catholic systemic schools, you can apply any time, but applying in Term 3 the year before entry is much smoother than applying mid-year. International applications usually need 4-6 months lead time for student visa processing.
What about kindergarten and preschool?
Each state runs slightly different early childhood pathways. The year before primary school (called Kindergarten in NSW, Prep in QLD/VIC, Reception in SA) is part of the public school system and free. Preschool/kindergarten for 3-4 year olds is run separately, often through community kinders or long day care centres, with varying state subsidies on top of the federal Child Care Subsidy.
What this finder doesn't include
- Specific school recommendations - we cannot rank schools; check My School data and visit schools yourself
- Catholic and independent school enrolment processes - these run on separate timelines and may require 2-3 years lead time at competitive schools
- Special needs and disability support - varies enormously by state and school; speak directly to schools
- International student fees for student visa holders
- Boarding school options - if your circumstances need this, see independent school websites directly
