The Illawarra Grammar School (TIGS) is an independent, Anglican, co-educational day school located at Mangerton in the Illawarra region of New South Wales, Australia.

The school currently caters for about 1100 pupils from pre-preparatory school to Year 12.


The Illawarra Grammar School was founded in 1959 through the efforts of the late Bishop Gordon Begbie and a dedicated band of 'founding parents' who firmly believed in the need for a regional Anglican School to be based in the Illawarra. On its opening day on 3 February 1959, the first Headmaster, Rev R F Bosanquet and two staff, welcomed 28 boys into "a close and caring community". According to Rev Bosanquet's Golden Jubilee address on 3 February 2009, 27 of the 28 boys came on the first day. In 1975, the school became co-educational when it amalgamated with SCEGGS ‘Gleniffer Brae’.[1] In 2009 TIGS celebrated the Golden Jubilee of its founding.[1]

In 2012 TIGS became an International Baccalaureate School, implementing the Primary Years Program (PYP) and the Middle Years Program (MYP).[2]
