The first Athletics Carnival was held at Olympic Park in September 1987. The Association, Country Grammar Schools, was formed at a principal’s meeting in 1987.

Competing schools were Hamilton College, St. Anne's & Gippsland Grammar School, Ballarat and Clarendon College, Girton College, Goulburn Valley Grammar School, Braemar College and Ballarat & Queen's Anglican Grammar School. The Carnival was run in year groups and the program has varied over the years.

The Scots' School joined in 1988 and Ballarat Grammar left. Ballarat and Clarendon left in 1992. St. Paul's Anglican Grammar School, Warragul, and Girton Grammar School Bendigo joined in 1993.

In 1998 St Anne’s and Gippsland Grammar School was renamed Gippsland Grammar. Bayview College joined in 2000.

Competing schools were St. Anne's and Gippsland Grammar School, Goulburn Valley Grammar School, Girton College, Hamilton College, Braemar College and Ballarat and Clarendon College.

A Cross Country was held at Girton College, Bendigo, in 1991. Competing schools were Scots, Braemar, Staggs, Girton, GVGS. Competition ceased because of concerns held over distance travelled to compete in one race.

In July 1996 a Cross-Country and debating competition was held at Mowbray College with a view to making this another permanent fixture in the association. Competing schools were; Staggs, Scots, Goulburn Valley, Mowbray, Girton and St Pauls.

Shields for Athletics Aggregate and Handicap were purchased in 1990 also minute book and container for house ribbons. The Constitution was written in 1994 with carnivals for Swimming and Athletics forming the competition.

The Winter Tour commenced in 1997 and involved hockey, basketball and netball. Competing schools were Scots, Goulburn Valley, St Paul’s, Girton and Hamilton.

Mrs Sharyn Canny has been appointed our inaugural ICCES Executive Officer. All directors were in favour that the new ICCES EO establish a separate and independent bank account with two signatories. Sharyn and I are in process of doing so with Commonwealth Bank.

2019 has been a productive year. I thank all Directors and Sport Coordinators for their support and prompt feedback. I especially thank Leigh Alexander for his enormous efforts as ICCES Assistant Secretary, my assistant Linda Archer and Ann Sutherland (THAC Payroll Officer) who generously managed the ICCES accounts. I look forward to working closely with Sharyn in 2020 to take ICCES forward and refine the quality experience that this wonderful sporting association provides our students.
