Sinai College commenced tuition as a Jewish Day School at the beginning of 1990, opening with 14 children enrolled in grades 1 to 5. First-year enrolments grew to 20 within seven months.
With the opening of the preschool and the extension of the primary school to year 6, enrolments increased to 53 during 1991.
The school grew larger over the next five years, requiring a significant extension of the campus in 1995.
Sinai College is housed in modern, purpose-built buildings situated in a bushland setting alongside the Jewish Communal Centre in the Southern Brisbane suburb of Burbank. The facilities include a number of classroom blocks, a newly restored swimming pool, tennis courts, playground, sports oval and the facilities of the community centre.
