Direct Answer
Casula High School, a comprehensive public high school in South Western Sydney, accepts international students, but with limited capacity in both 2026 and 2027. As of the 1 June 2026 NSW Department of Education capacity update, the school offers limited places for Years 7, 8, 9, and 10 in 2026, and expands to include Year 11 in 2027. A key condition is that all international students must have a confirmed address within the school’s designated catchment area. The school does provide English as an Additional Language/Dialect (EAL/D) support for international students. However, homestay availability is not specified by the NSW DoE, meaning families must independently arrange accommodation. There is no cannot guarantee placement (subject to availability and DE International assessment), as enrolments are subject to capacity, availability, and assessment by DE International. This article details the year-level openings, catchment rules, and support services available for prospective international students and their families.
Open Year Levels: 2026 vs 2027
The available year levels for international students at Casula High School differ slightly between 2026 and 2027.
2026 Enrolment:
- Status: Limited
- Open year levels: 7, 8, 9, 10
- Details: Only these four year levels have capacity for new international student enrolments. Year 11 and Year 12 are not available in 2026.
2027 Enrolment:
- Status: Limited
- Open year levels: 7, 8, 9, 10, 11
- Details: In 2027, capacity expands to include Year 11, offering a pathway for students who wish to begin their senior studies at Casula. Year 12 remains unavailable in this update.
This expansion from 2026 to 2027 is notable for families planning ahead. If you are targeting a 2026 start, you cannot enrol in Year 11 or Year 12. For a 2027 start, Year 11 becomes an option, though places remain limited and subject to availability. As stated by the NSW Department of Education, the capacity data used in this article is a guide only and there is no cannot guarantee placement (subject to availability and DE International assessment).
Catchment Area and Accommodation
A critical requirement for Casula High School is that international students must have a confirmed address within the school’s designated catchment area. This means that, unlike some NSW public high schools that accept out-of-area enrolments, Casula strictly requires proof of residence within its local intake zone. Families should verify their address against the school’s catchment boundaries using the NSW Department of Education’s School Finder tool before applying.
Homestay: The NSW DoE capacity update does not specify homestay availability for Casula High School. This means the school does not have a formal homestay arrangement listed through DE International. Families must therefore arrange their own accommodation independently, whether through private homestay providers, renting a property within the catchment area, or living with relatives who reside in the zone. This adds an extra layer of planning for prospective students.
English Language Support (EAL/D)
Casula High School offers English as an Additional Language/Dialect (EAL/D) support for international students. This is a significant advantage for students who need language assistance while adjusting to the Australian curriculum.
The EAL/D program is designed to help non-native English speakers develop their academic English skills across all subjects. It typically includes:
- Targeted in-class support from specialist teachers.
- Small group or individual sessions focused on vocabulary, writing, and comprehension.
- Assessment of English proficiency upon arrival to determine the level of support needed.

- Students entering Years 7 to 10 in 2026, or Years 7 to 11 in 2027, who are comfortable with limited capacity and competitive placement.
