all curriculum areas, and has been marketed overseas. In 2020, a new STEM building was added to facilitate the schools growing population of students in engineering, biology, physics and more. Costing around $10 million, it consists of three storeys, in which include a lecture theatre, several labs, designated "study areas" and a balcony. Headmasters Campus The original school buildings from the 1860s still sit on the crown of Grammar School Hill, with the original building now known as the 'Great Hall'. These buildings are now listed by the National Trust of Australia. The school grounds themselves have undergone a notable transformation in recent years, with the most significant change being the introduction of the Igor Lapa Junior School. Now included within the Igor Lapa Junior School is a full indoor sand volleyball pit and some basketball hoops with cricket pitches marked out on them. Some further extensions have been made to the junior school due to the new attendance of prep to grade three. Recently, the Board of Trustees approved expansion of the Prep buildings, and refurbishment of the remaining Tennis Court at Ipswich Grammar's main campus. Due to this expansion of the Prep building over the Tennis courts, additional Courts have been made at the school's externally owned land in Brassall. This land is usually used for cross country, cricket, rugby and soccer in the appropriate seasons. Eight new Tennis courts were constructed at the Brassall grounds during the 2008 Christmas break for GPS competition and training for the students. Ipswich Grammar School, recently occupied the services of Stonestreets Coaches and Doyles Coaches, to do the school's charter routes. GPS membership IGS is a member of the Great Public Schools Association of Queensland, better known as the GPS, which was established in 1918. IGS was one of the founding members. Today, nine schools are involved in the GPS system, being IGS, Nudgee College, Gregory Terrace, Brisbane Grammar School, Toowoomba Grammar School, Anglican Church Grammar School, Brisbane State High School, The Southport School and Brisbane Boys' College. Thirteen formal GPS Activities are engaged in between the schools, with Premierships for each activity awarded each year. Despite being among the smaller of the GPS Schools in terms of student attendance, IGS performs well in a number of GPS competitions, chief amongst them the annual Track and Field competition, which was claimed by Ipswich Grammar thirteen times in fifteen years from 1998
