St Gregory’s College, Campbelltown is a Catholic K–12 day and boarding school located in Gregory Hills, south-west of Sydney. Founded in 1926 on the original property of Thomas Donovan, the school was established with a clear purpose: to educate boys from regional and rural communities and give them a pathway into practical, agricultural and academic careers. The Marist Brothers assumed control in 1929 and have continued to oversee the college to the present day.
Originally known as St Gregory’s Agricultural College, the campus operated for decades with a full working farm including dairy, poultry, pigs and rodeo facilities across more than 400 hectares. Much of this land was later sold for the development of Gregory Hills, but agriculture remains part of the school’s identity, with a scaled farm, show cattle and sheep programmes, and participation in major events such as the Sydney Royal Easter Show, Camden Show and Dubbo Show.
The modern college is a dual-structure school: co-educational K–6, and boys-only Years 7–12, with around 1,100 students and approximately 180 boarders. Boarding remains central to the school’s culture, particularly for students from rural NSW. The campus sits on one consolidated hilltop site and includes academic buildings, specialist facilities, a chapel, sporting fields and a range of boarding houses named after key Marist figures.
Sport is a defining part of St Gregory’s. The college has long been regarded as one of Australia’s strongest school nurseries for rugby league talent, with dozens of former students progressing to NRL clubs, representative sides, coaching and elite pathways. Alongside league, the college competes in rugby union, cricket, football, basketball, water polo, athletics and a wide spread of ISA and MCS sporting competitions. Water polo and cricket have delivered multiple championships, and rugby league remains the school’s flagship sport with deep community support and a structured programme across all grades.
Beyond sport, St Gregory’s has an active co-curricular programme including debating, public speaking, the CSDA competition, Marist Oratory, music, performing arts and community initiatives. The school also maintains a strong connection to its Marist heritage and Catholic ethos through liturgy, pastoral care and service opportunities.
Across nearly a century of operation, St Gregory’s has produced a wide range of notable alumni in elite sport, public service, defence, politics, the arts and agriculture. The college remains a significant educational institution in the Diocese of Wollongong and continues to serve both day students from the growing Camden–Campbelltown corridor and boarders from wider regional NSW.
