Five NSW Senior Colleges That Only Take Year 11–12 (and One for Over-18s)

Direct Answer

Yes—there are five NSW public senior colleges that accept international students and are purpose‑built for the final years of secondary school. Four of them enrol only Year 11 students (effectively offering Years 11–12), while one, Bankstown Senior College, is a flexible over‑18s campus that offers Year 10 and Year 11.

According to the NSW Department of Education’s International Students Capacity Update of 1 June 2026:

St Marys Senior High School has capacity for Year 11 in both 2026 and 2027.
Callaghan College – Jesmond Senior Campus, Georges River College – Oatley Senior Campus, and Sydney Secondary College – Blackwattle Bay Campus will not accept new international enrolments in 2026, but will each have Year 11 capacity in 2027.
Bankstown Senior College is the only senior college dedicated to students aged 18 years and over. It has capacity in Year 10 in 2026, and Years 10 and 11 in 2027, operates without a uniform, and runs only four days a week.

As stated by the NSW Department of Education, the capacity data is a guide only and there is no guarantee of placement. All information is current as of 1 June 2026.

What Is a Senior College in NSW?

A NSW senior college is a public high school that focuses exclusively on Stage 6 (Years 11 and 12). Unlike comprehensive high schools, these campuses do not enrol students in Years 7–10. The result is an environment that more closely resembles a pre‑university or adult‑learning setting: students are treated as young adults, timetables often allow for independent study, and there may be no traditional school uniform.

For international students, a senior college can be an ideal pathway to the NSW Higher School Certificate (HSC). Because the student body is restricted to older teenagers, the culture is academically focused, and the transition to university life can feel smoother. Some senior colleges also accept small numbers of Year 10 students under specific conditions, but the core offering is Year 11 entry leading to Year 12 graduation.

The five colleges below are the only NSW public senior colleges currently listed with international student capacity. Note that three of them are part of a larger collegiate structure (Callaghan, Georges River, Sydney Secondary) but operate a separate senior campus.

Which NSW Senior Colleges Have International Student Capacity in 2027?

The following roster summarises the five senior colleges that feature in the NSW Department of Education’s 1 June 2026 update. All entries list capacity for international students (temporary residents) only. Use this as a planning guide, not a guarantee.

Bankstown Senior College – South Western Sydney
Over‑18s only.
- 2026: Capacity in Year 10
- 2027: Capacity in Years 10 and 11
- No school uniform; four‑day school week
Callaghan College – Jesmond Senior Campus – Newcastle
Senior school only.
- 2026: Cannot accept any enrolments
- 2027: Capacity in Year 11 only
Georges River College – Oatley Senior Campus – Southern Sydney
Senior school only.
- 2026: Cannot accept any enrolments
- 2027: Capacity in Year 11 only
St Marys Senior High School – Western Sydney
Senior school only.
- 2026: Capacity in Year 11 only
- 2027: Capacity in Year 11 only
Sydney Secondary College – Blackwattle Bay Campus – Inner Western Sydney
Senior school only.
- 2026: Cannot accept any enrolments
- 2027: Capacity in Year 11 only

Key takeaway: Only St Marys Senior High School is open for Year 11 international students in 2026. If you are aiming for a 2027 start, all four standard senior colleges plus Bankstown become available. Because places are limited, early preparation is essential.

Bankstown Senior College: The Over‑18s Option

Among the five campuses, Bankstown Senior College stands apart. It is the only NSW public senior college explicitly designated for students aged 18 years and over. This makes it a unique option for international students who:

have had a delayed start to secondary school,
are returning to education after a gap, or
want a less traditional, more independent senior school experience.

Bankstown offers Year 10 in 2026 and Years 10 and 11 in 2027. There is no Year 12 intake, so students follow a sequential two‑ or three‑year pathway to the HSC. The college operates four days a week, has no school uniform, and provides an adult‑learning atmosphere that many mature students prefer.

Visa considerations for over‑18 students

Who This Is For (And Who It’s Not)

Suitable for:

International students currently in Year 10 or 11 abroad who want to complete the HSC in a dedicated senior campus, either starting in 2026 (St Marys or Bankstown) or planning for 2027.
Mature students aged 18 and over who still need to finish Years 10–11 and value the flexible, four‑day‑a‑week, no‑uniform structure of Bankstown Senior College.
Students who thrive in a self‑directed, adult‑like learning environment, where they are treated as responsible young adults.
Families prepared to apply early—most of these schools will not accept new international students until 2027, so timing and planning are critical.

Not suitable for:

Students younger than 15. Even the Year 10 offering at Bankstown requires students to be over 18, and the other senior campuses only accept Year 11 students (typically 16–18 years old).
Those wanting a full 7–12 high school experience with a broad mix of age groups, extensive extracurriculars, or a uniform‑based culture.
Students needing immediate 2026 Year 11 entry at Callaghan, Georges River, or Sydney Secondary Blackwattle Bay—they have no capacity until 2027.
Over‑18 applicants who cannot meet visa, welfare, or guardianship requirements associated with living independently in Australia.

Frequently Asked Questions

Q: Can I enrol directly in Year 12 at a NSW senior college?
A: No. All five senior colleges list capacity only for Year 10 or Year 11. The senior‑school‑only campuses (Callaghan Jesmond, Georges River Oatley, St Marys, Sydney Secondary Blackwattle Bay) accept Year 11 only. Bankstown Senior College accepts Year 10 and Year 11 but not Year 12. To complete the HSC as an international student, you must enter at a point that allows the full two‑year Stage 6 program.

Q: Do any of these senior colleges accept students under 18?
A: Yes. Callaghan College Jesmond, Georges River Oatley, St Marys, and Sydney Secondary Blackwattle Bay are standard senior colleges that typically enrol students aged 16–18. There is no over‑18 restriction at those four schools. Bankstown, however, is only for students aged 18 and over.

Q: What if I am over 18 but want to attend a standard senior college, not Bankstown?
A: Over‑18 students may still be accepted at the other four senior colleges (subject to Department of Education age policies and visa conditions), but those schools are not exclusively designed for adults. Bankstown is the only senior college with a dedicated over‑18 mission, a four‑day week, and no uniform. Whether you choose Bankstown or another campus, over‑18 international students must meet all visa, welfare, and accommodation requirements. Discuss your situation with an education agent early.

Q: How can I improve my chances of getting a place at these schools?

Data Source and Methodology

The information in this article comes from the NSW Department of Education’s International Students Capacity Update, dated 1 June 2026. This official document lists all NSW public schools open to temporary resident (international) students and the year levels for which they have capacity in the 2026 and 2027 academic years.

We extracted the list of schools that are either designated “senior only” or have an explicit over‑18 age requirement, then verified each school’s capacity notes and conditions. No other schools were included.

Important caveat: The capacity update is a guide only. Actual enrollment depends on the number of applications, the student’s individual circumstances, English language proficiency, and the Department’s assessment. There is no guarantee of placement. Always contact the NSW Department of Education or a registered education agent for the most up‑to‑date advice before applying.
