Macarthur is located in Cobbitty, in semi-rural south-western Sydney, about 50 minutes from Sydney Airport and just one hour from the Sydney CBD.
Macarthur has an extensive 85 acre site. An ongoing building programme ensures that students are educated in facilities that are outstanding in their design and function. Classrooms are modern, well-lit and air-conditioned.
Specialist rooms for Technology, Music, Visual Arts and Science are well designed and equipped. The School Chapel, apart from being the venue for regular Chapel Services, serves as an excellent venue for performance activities such as concerts, plays, musicals and recitals.
New classrooms were constructed in 2010 to house Year 5 and Year 6. In addition, a multipurpose centre was built adjacent to the St Paul's classroom block. An extension to the Stoddart Centre now houses the Cramner meeting room and Senior Students Study.
The Stoddart Centre is also home to the Innovation and Research Centre which is at the heart of the Academic Culture of the School.
The expansive grounds allow for the continuing development of sporting facilities. An Olympic size athletics field, together with long jump, discus and shot put facilities, allows for school and inter-school athletics carnivals to be held on site. The School has its own 6 kilometre cross-country running track. The gymnasium, which is also used for School Assemblies, contains a full-sized basketball court. There are tennis and netball courts, cricket nets and a soccer field. Additional sporting facilities are planned for the future.
The ample space of the school site lends itself to the site's historical use as a farm from early colonial times. More about the School Farm.
