Adelaide’s top public schools — Glenunga International, Adelaide High, Brighton Secondary, Marryatville High, Unley High, and Norwood Morialta — consistently lead South Australia for academic results, specialist programs, and SACE outcomes. This guide walks parents through the 10 strongest government schools in Adelaide, how zoning works, which suburbs sit inside each catchment, the IB and specialist-music pathways, and what to weigh up before you commit your child to a six-year journey.
Updated for the 2026 enrolment cycle, with figures from the South Australian Department for Education, MySchool, and the SACE Board of South Australia. If you’d rather skip the listicle and book a tutor for your child, Tutero matches Adelaide families with a verified tutor in 48 hours from A$65/hr.
Quick answer: which public schools in Adelaide are the best?
Glenunga International High School is the most-cited top performer, followed by Adelaide High, Brighton Secondary, Marryatville High, Unley High, and Norwood Morialta. Each one combines strong NAPLAN and SACE results with a specialist program: International Baccalaureate at Glenunga and Unley, Special Interest Music at Marryatville and Brighton, languages at Adelaide High, and Special Interest Cricket and Rugby at Brighton. The “best” school for your child depends less on the league table and more on whether you live inside the zone and whether the specialist program matches what your child is good at.
How does Adelaide public school zoning work?
South Australia runs a residential-address zoning system for public schools: each government school has a defined catchment area, and if your home address sits inside it, your child has a guaranteed enrolment right. If you live outside the zone, the school can only enrol your child if it has surplus capacity, which the most popular schools rarely do. The Department for Education publishes every zone map on its school-zone finder; type your suburb in and it returns the catchment primary, secondary, and combined schools you’re entitled to. Zones for Glenunga International, Adelaide High, Brighton Secondary, and Norwood Morialta are tightly drawn and have been redrawn at least once in the past decade as enrolment pressure has grown.
How do I get into Adelaide High School?
There are three ways into Adelaide High School. The first is residential zoning — if you live inside the Adelaide High catchment (parts of the CBD, North Adelaide, Hindmarsh, Bowden, and the immediate inner-west), your child has a guaranteed place from Year 7. The second is the Special Entry program for Languages, Music, Rowing, or Cricket, which accepts a small number of students each year from outside the zone based on audition or trial. The third is the International Baccalaureate Middle Years pathway, also competitively assessed. Applications for special-entry pathways open in Term 1 of the year before the student starts; auditions and trials run through Term 2 and Term 3.
What's the best government school in Adelaide?
If you’re asking purely about academic outcomes, Glenunga International High School is consistently the highest-ranked government school in South Australia by SACE merit count and NAPLAN results, and it’s a top-five government school in Australia by The Advertiser’s 2025 ranking. But “best” depends on what you’re optimising for: Brighton Secondary is unbeatable if your child is a serious musician or volleyball player; Marryatville is the standout for music auditioning students; Adelaide High suits language-focused or central-living families; Norwood Morialta wins on global-education programs and breadth of vocational options. The strongest fit beats the highest league-table position every time.
Which Adelaide public schools offer the IB?
Two Adelaide public secondary schools offer the International Baccalaureate Diploma Programme alongside SACE: Glenunga International High School and Unley High School. A handful also offer the IB Middle Years Programme: Glenunga, Adelaide High, and Aberfoyle Park High. The IB Diploma is a two-year senior-secondary qualification (Years 11 and 12) that’s recognised by every Australian university through ATAR conversion, and it’s particularly useful for students who want to study overseas. Entry into IB classes is internal application within the school in Year 10; not every Year 11 enrolled at Glenunga or Unley sits the IB — the majority still sit SACE. If your child is academically ambitious, the IB pathway at Glenunga is one of the strongest reasons to live inside that zone.
Which Adelaide public schools have specialist music programs?
Five Adelaide public schools run formal Special Interest Music programs: Marryatville High School (the most established, with a national reputation), Brighton Secondary School (large program, instrumental and vocal streams), Woodville High School, Mitcham Girls High School, and Para Hills High School. Special Interest Music is an audition-entry program available to students living outside the zone — if your child plays an instrument seriously and lives nowhere near Marryatville or Brighton, the audition is the way in. Auditions for Year 8 entry happen in Term 3 of the Year 7 year; students prepare two contrasting pieces and a short sight-reading test. The Department maintains the full list of special-interest programs, including sport-focused programs like Brighton’s Special Interest Cricket and Volleyball. If your child needs supplementary support to prepare for an audition or zone-entry assessment, a one-on-one English tutor or maths tutor can fill the gap.
Which Adelaide suburbs have the best public schools?
Suburbs in Adelaide’s inner-east and inner-south consistently sit inside the zones for the highest-performing public schools. Glenunga, Linden Park, Beaumont, and Glen Osmond are zoned to Glenunga International. Adelaide CBD, North Adelaide, Bowden, Hindmarsh, and parts of Thebarton are zoned to Adelaide High. Brighton, Glenelg South, Seacliff, Marino, and parts of Somerton Park are zoned to Brighton Secondary. Marryatville, Kensington Park, Beulah Park, and St Morris fall inside the Marryatville High catchment. Unley, Hyde Park, Wayville, Malvern, and parts of Goodwood are zoned to Unley High. The trade-off in every case is property prices — in 2025 the Glenunga and Marryatville catchments commanded a measurable premium over neighbouring suburbs that fall just outside the line.
Are Adelaide public schools as good as private schools?
For academic results, yes — the top public schools in Adelaide are competitive with the top private schools on SACE merits, ATAR distribution, and university offers. Glenunga International routinely produces more SACE merits than several Adelaide private schools that charge A$30,000+ in Year 12 fees. The honest gaps are: smaller class sizes at private schools (typically 18–22 students versus 25–30 in public secondary), more extensive co-curricular budgets (boatsheds, dedicated chaplaincy, larger camp programs), and tighter alumni networks. The flip side: zero tuition fees, more diverse student cohorts, and specialist programs that rival or exceed the private sector — particularly for music, languages, and IB. Most Adelaide families who can afford either choose based on fit and proximity, not perceived prestige.
The 10 top-performing public schools in Adelaide
1. Glenunga International High School
Glenunga International, in Adelaide’s eastern suburbs, is widely regarded as the highest-performing public secondary school in South Australia. With over 2,300 students, it offers both SACE and the full International Baccalaureate Diploma Programme, plus an Ignite gifted-and-talented stream from Year 8. Strong language program (French, German, Japanese, Chinese), broad co-curricular offerings, and consistently top-tier SACE merit results. Glenunga’s zone covers Glenunga, Linden Park, Beaumont, Glen Osmond, and parts of Burnside.
2. Adelaide High School
Founded in 1908, Adelaide High School is the city’s flagship public school and one of South Australia’s oldest. Year 8–12 co-educational, with Special Entry pathways for Languages, Music, Rowing, and Cricket open to students outside the zone. Strong record on SACE merits, particularly in languages (French, German, Italian, Greek, Spanish, Vietnamese) and humanities. Central-city location, smaller cohort than Glenunga, and an unusually strong rowing program for a public school.
3. Brighton Secondary School
A large coastal secondary school in Adelaide’s south-west, Brighton Secondary is best known for its Special Interest Music Program (audition entry, full SACE pathway with music-major specialisation) and Special Interest Volleyball and Cricket programs. Strong general academic results, particularly in mathematics and science, and a large enough cohort to offer a wide range of SACE subjects. Catchment includes Brighton, Glenelg South, Seacliff, and Marino.
4. Marryatville High School
In Adelaide’s leafy inner-east, Marryatville High School runs the most established Special Interest Music program in South Australia — orchestra, choir, jazz ensemble, and instrumental tuition built into the timetable. Strong overall academic outcomes, with above-average SACE merit counts. Marryatville also runs a Special Interest Tennis program and has a particularly active arts and drama program.
5. Unley High School
A high-performing co-educational school in Adelaide’s inner-south, Unley High offers SACE and the IB Diploma. Strong STEM program, dedicated student wellbeing structure, and a broad elective offering across physics, chemistry, digital technologies, performing arts, and humanities. Catchment includes Unley, Hyde Park, Wayville, Malvern, and parts of Goodwood.
6. Norwood Morialta High School
In the inner-east, Norwood Morialta runs a consistent SACE program with strong vocational pathways alongside academic streams. Established global-education program with international exchanges and study tours, robotics, and a notable leadership program for senior students. Two-campus structure (Middle School at Morialta, Senior School at Norwood) gives Year-10 students a genuine secondary-to-senior transition.
7. Heathfield High School
In the Adelaide Hills, Heathfield High is the strongest public secondary option for families east of Stirling. SACE outcomes are consistently solid; the school runs Special Interest Soccer and a well-regarded outdoor education stream. Catchment covers Heathfield, Aldgate, Bridgewater, Mylor, and parts of Crafers.
8. Mitcham Girls High School
Adelaide’s only single-sex public secondary school for girls, Mitcham Girls runs Special Interest Music and a strong languages program (French, Spanish, Vietnamese, Japanese), plus the Mitcham Girls’ STEM Academy. Above-average SACE results and strong alumni outcomes in medicine, engineering, and law.
9. Aberfoyle Park High School
Aberfoyle Park, in the southern suburbs, is one of only three SA public schools to offer the IB Middle Years Programme. Strong general SACE performance, particularly in arts and design, and a substantial Aboriginal Education Program. Catchment includes Aberfoyle Park, Flagstaff Hill, Happy Valley, and parts of O’Halloran Hill.
10. The Heights School (Modbury Heights)
In Adelaide’s north-east, The Heights is a single-campus R–12 school (one of the largest in SA) with a Special Interest Science and Mathematics Academy and a strong Music program. Above-average SACE results across STEM, and a genuine R–12 progression that suits families who want school-stage continuity.
How do I choose the right public school in Adelaide?
Five things to weigh up, in order of impact:
- Are you in the zone? Use the Department for Education zone finder first. If you’re inside the zone for one of the top schools, the decision often makes itself. If you’re not, your real options are special-entry programs (music, sport, languages) or moving suburb.
- Match the specialist program to your child. A child who already plays an instrument seriously will get more from Marryatville or Brighton’s music program than from Glenunga’s general academic stream. A child planning to study overseas benefits from Glenunga or Unley’s IB. A linguistically inclined child fits Adelaide High.
- Read the recent SACE results, not the historical reputation. Public-school performance shifts over a 5–10 year window. Look at the most recent two years of merit counts and ATAR median, not what the school was famous for a decade ago.
- Visit the school in session. Open days are stage-managed; a Tuesday-morning visit to reception with the question “may I look around the senior-school courtyard at recess?” tells you more about the day-to-day culture than any glossy prospectus.
- Talk to current parents. Two or three honest conversations with parents whose children are in Year 11 or Year 12 right now will give you a far better read than any rankings table.
What are the disadvantages of Adelaide public schools?
The honest trade-offs of choosing public over private in Adelaide are: larger class sizes (typically 25–30 in core SACE subjects, versus 18–22 in private schools), thinner co-curricular budgets (smaller camp programs, fewer cross-school sport opportunities, less in the way of polished facilities), and a stricter zoning system that means your address often makes the choice for you. The newer SA public schools also tend to have plainer infrastructure than long-established private schools — functional rather than impressive. None of this affects academic outcomes at the top public schools, but it’s worth being honest about what you’re trading. If your child is finding any subject hard despite a strong school, an outside-school tutor can fill the gap that a 30-student class can’t. Tutero matches Adelaide families with a verified Year 7–12 tutor in 48 hours, online or in-person, from A$65/hr with no contracts.

The bottom line
Adelaide’s top public schools — led by Glenunga International, Adelaide High, Brighton Secondary, Marryatville High, Unley High, and Norwood Morialta — deliver academic outcomes that genuinely compete with the city’s top private schools, often at zero tuition cost. The biggest decision is rarely the league table; it’s whether you sit inside the right zone and whether the specialist program matches what your child is good at. Check your zone, match the program to your child, look at recent SACE results, and visit the school in session. The right public school in Adelaide can give your child a top-tier education without the A$30,000-a-year fee. If your child needs extra support outside school, Tutero pairs Adelaide students with a verified tutor from A$65/hr, no contracts.

Special Interest Music is an audition-entry program available to students living outside the zone — if your child plays an instrument seriously and lives nowhere near Marryatville or Brighton, the audition is the way in. Auditions for Year 8 entry happen in Term 3 of the Year 7 year; students prepare two contrasting pieces and a short sight-reading test. The Department maintains the full list of special-interest programs, including sport-focused programs like Brighton’s Special Interest Cricket and Volleyball. If your child needs supplementary support to prepare for an audition or zone-entry assessment, a one-on-one English tutor or maths tutor can fill the gap.
Which Adelaide suburbs have the best public schools?
Suburbs in Adelaide’s inner-east and inner-south consistently sit inside the zones for the highest-performing public schools. Glenunga, Linden Park, Beaumont, and Glen Osmond are zoned to Glenunga International. Adelaide CBD, North Adelaide, Bowden, Hindmarsh, and parts of Thebarton are zoned to Adelaide High. Brighton, Glenelg South, Seacliff, Marino, and parts of Somerton Park are zoned to Brighton Secondary. Marryatville, Kensington Park, Beulah Park, and St Morris fall inside the Marryatville High catchment. Unley, Hyde Park, Wayville, Malvern, and parts of Goodwood are zoned to Unley High. The trade-off in every case is property prices — in 2025 the Glenunga and Marryatville catchments commanded a measurable premium over neighbouring suburbs that fall just outside the line.
Are Adelaide public schools as good as private schools?
For academic results, yes — the top public schools in Adelaide are competitive with the top private schools on SACE merits, ATAR distribution, and university offers. Glenunga International routinely produces more SACE merits than several Adelaide private schools that charge A$30,000+ in Year 12 fees. The honest gaps are: smaller class sizes at private schools (typically 18–22 students versus 25–30 in public secondary), more extensive co-curricular budgets (boatsheds, dedicated chaplaincy, larger camp programs), and tighter alumni networks. The flip side: zero tuition fees, more diverse student cohorts, and specialist programs that rival or exceed the private sector — particularly for music, languages, and IB. Most Adelaide families who can afford either choose based on fit and proximity, not perceived prestige.
The 10 top-performing public schools in Adelaide
1. Glenunga International High School
Glenunga International, in Adelaide’s eastern suburbs, is widely regarded as the highest-performing public secondary school in South Australia. With over 2,300 students, it offers both SACE and the full International Baccalaureate Diploma Programme, plus an Ignite gifted-and-talented stream from Year 8. Strong language program (French, German, Japanese, Chinese), broad co-curricular offerings, and consistently top-tier SACE merit results. Glenunga’s zone covers Glenunga, Linden Park, Beaumont, Glen Osmond, and parts of Burnside.
2. Adelaide High School
Founded in 1908, Adelaide High School is the city’s flagship public school and one of South Australia’s oldest. Year 8–12 co-educational, with Special Entry pathways for Languages, Music, Rowing, and Cricket open to students outside the zone. Strong record on SACE merits, particularly in languages (French, German, Italian, Greek, Spanish, Vietnamese) and humanities. Central-city location, smaller cohort than Glenunga, and an unusually strong rowing program for a public school.
3. Brighton Secondary School
A large coastal secondary school in Adelaide’s south-west, Brighton Secondary is best known for its Special Interest Music Program (audition entry, full SACE pathway with music-major specialisation) and Special Interest Volleyball and Cricket programs. Strong general academic results, particularly in mathematics and science, and a large enough cohort to offer a wide range of SACE subjects. Catchment includes Brighton, Glenelg South, Seacliff, and Marino.
4. Marryatville High School
In Adelaide’s leafy inner-east, Marryatville High School runs the most established Special Interest Music program in South Australia — orchestra, choir, jazz ensemble, and instrumental tuition built into the timetable. Strong overall academic outcomes, with above-average SACE merit counts. Marryatville also runs a Special Interest Tennis program and has a particularly active arts and drama program.
5. Unley High School
A high-performing co-educational school in Adelaide’s inner-south, Unley High offers SACE and the IB Diploma. Strong STEM program, dedicated student wellbeing structure, and a broad elective offering across physics, chemistry, digital technologies, performing arts, and humanities. Catchment includes Unley, Hyde Park, Wayville, Malvern, and parts of Goodwood.
6. Norwood Morialta High School
In the inner-east, Norwood Morialta runs a consistent SACE program with strong vocational pathways alongside academic streams. Established global-education program with international exchanges and study tours, robotics, and a notable leadership program for senior students. Two-campus structure (Middle School at Morialta, Senior School at Norwood) gives Year-10 students a genuine secondary-to-senior transition.
7. Heathfield High School
In the Adelaide Hills, Heathfield High is the strongest public secondary option for families east of Stirling. SACE outcomes are consistently solid; the school runs Special Interest Soccer and a well-regarded outdoor education stream. Catchment covers Heathfield, Aldgate, Bridgewater, Mylor, and parts of Crafers.
8. Mitcham Girls High School
Adelaide’s only single-sex public secondary school for girls, Mitcham Girls runs Special Interest Music and a strong languages program (French, Spanish, Vietnamese, Japanese), plus the Mitcham Girls’ STEM Academy. Above-average SACE results and strong alumni outcomes in medicine, engineering, and law.
9. Aberfoyle Park High School
Aberfoyle Park, in the southern suburbs, is one of only three SA public schools to offer the IB Middle Years Programme. Strong general SACE performance, particularly in arts and design, and a substantial Aboriginal Education Program. Catchment includes Aberfoyle Park, Flagstaff Hill, Happy Valley, and parts of O’Halloran Hill.
10. The Heights School (Modbury Heights)
In Adelaide’s north-east, The Heights is a single-campus R–12 school (one of the largest in SA) with a Special Interest Science and Mathematics Academy and a strong Music program. Above-average SACE results across STEM, and a genuine R–12 progression that suits families who want school-stage continuity.
How do I choose the right public school in Adelaide?
Five things to weigh up, in order of impact:
- Are you in the zone? Use the Department for Education zone finder first. If you’re inside the zone for one of the top schools, the decision often makes itself. If you’re not, your real options are special-entry programs (music, sport, languages) or moving suburb.
- Match the specialist program to your child. A child who already plays an instrument seriously will get more from Marryatville or Brighton’s music program than from Glenunga’s general academic stream. A child planning to study overseas benefits from Glenunga or Unley’s IB. A linguistically inclined child fits Adelaide High.
- Read the recent SACE results, not the historical reputation. Public-school performance shifts over a 5–10 year window. Look at the most recent two years of merit counts and ATAR median, not what the school was famous for a decade ago.
- Visit the school in session. Open days are stage-managed; a Tuesday-morning visit to reception with the question “may I look around the senior-school courtyard at recess?” tells you more about the day-to-day culture than any glossy prospectus.
- Talk to current parents. Two or three honest conversations with parents whose children are in Year 11 or Year 12 right now will give you a far better read than any rankings table.
What are the disadvantages of Adelaide public schools?
The honest trade-offs of choosing public over private in Adelaide are: larger class sizes (typically 25–30 in core SACE subjects, versus 18–22 in private schools), thinner co-curricular budgets (smaller camp programs, fewer cross-school sport opportunities, less in the way of polished facilities), and a stricter zoning system that means your address often makes the choice for you. The newer SA public schools also tend to have plainer infrastructure than long-established private schools — functional rather than impressive. None of this affects academic outcomes at the top public schools, but it’s worth being honest about what you’re trading. If your child is finding any subject hard despite a strong school, an outside-school tutor can fill the gap that a 30-student class can’t. Tutero matches Adelaide families with a verified Year 7–12 tutor in 48 hours, online or in-person, from A$65/hr with no contracts.

The bottom line
Adelaide’s top public schools — led by Glenunga International, Adelaide High, Brighton Secondary, Marryatville High, Unley High, and Norwood Morialta — deliver academic outcomes that genuinely compete with the city’s top private schools, often at zero tuition cost. The biggest decision is rarely the league table; it’s whether you sit inside the right zone and whether the specialist program matches what your child is good at. Check your zone, match the program to your child, look at recent SACE results, and visit the school in session. The right public school in Adelaide can give your child a top-tier education without the A$30,000-a-year fee. If your child needs extra support outside school, Tutero pairs Adelaide students with a verified tutor from A$65/hr, no contracts.
South Australia uses residential-address zoning: each public school has a defined catchment, and if your home address is inside it, your child has a guaranteed enrolment right. Outside-zone enrolments are only granted when the school has surplus capacity. The Department for Education's school-zone finder returns the catchment schools for any Adelaide suburb.
Glenunga International High School and Unley High School offer the full IB Diploma Programme alongside SACE. Glenunga, Adelaide High, and Aberfoyle Park High also offer the IB Middle Years Programme. IB enrolment within these schools is by internal application in Year 10; most students still sit SACE rather than IB.
Three pathways: (1) residential zoning — guaranteed if you live in the catchment (CBD, North Adelaide, Hindmarsh, Bowden, parts of the inner-west); (2) Special Entry programs for Languages, Music, Rowing, or Cricket, by audition or trial; (3) the IB Middle Years pathway by competitive assessment. Special-entry applications open Term 1 of the year before starting.
Five Adelaide public secondary schools run audition-entry Special Interest Music programs: Marryatville High School, Brighton Secondary School, Woodville High School, Mitcham Girls High School, and Para Hills High School. Auditions for Year 8 entry happen in Term 3 of the Year 7 year and require two contrasting prepared pieces plus sight-reading.
On academic outcomes, the top Adelaide public schools — particularly Glenunga International — are competitive with the top private schools on SACE merits and ATAR distribution. Private schools typically offer smaller class sizes (18–22 versus 25–30) and larger co-curricular budgets, but at A$30,000+ in Year 12 fees. Public schools charge zero tuition.
Adelaide tutoring rates typically run A$55–A$85 per hour. Tutero matches Adelaide families with a verified tutor from A$65 per hour for any year level — primary, lower-secondary, or senior — with no contracts and 48-hour matching online or in-person.
