Our School

Our History

International Grammar School opened in 1984 in the Stanley Street premises of the Little Sisters of the Poor, Randwick, with 44 students ranging from Kindergarten to Year 11. By the end of that first year there were 123 students and by first term in 1985 enrolments had grown to 231.

Several years later, having lost the lease at Randwick, the school moved to the old Elizabeth Arden cosmetics factory in Riley Street, Surry Hills. The old buildings were converted into a school in the space of six weeks. With expanding enrolments and the need for specialized high school teaching facilities, an additional site was required, and from 1990 to 1994 premises in Balmain were employed as a Senior High School, accommodating Years 11 and 12.

In 1995 the high school moved to a temporary site in Mountain Street, Ultimo, and in 1997 the whole school moved to premises constructed on the historical site of the Dalgety Woolstore in Kelly Street, Ultimo. The architects sought a spectacular and colourful design appropriate for the school's city location, incorporating its historical facade with the modern aesthetics of the building.

In 2005 the school opened the Senior Annexe in a converted warehouse building in Mountain Street, very close to the Kelly Street building. This has enabled us to introduce new learning spaces and opportunities across the full range of school activities.
