In 1918, the British colonial government established its first school in Suva.

In 2004 the school, in cooperation with police, launched a pilot "Scholastic Crime Stoppers" programme targeting drug use, truancy and other problems.

In 2008, members of the Suva Grammar Old Students Association made a request to the Fijian Minister for Education for school principal Ilikimi Kunagogo to be removed.

In 2011, in conjunction with the Ministry of Health, Grammar heads signed a partition in which Suva Grammar School was declared the first drug-free secondary institution in the country.
