[3] The college consists of three main metropolitan campuses in Melbourne, St Kilda Road, Glen Waverley and Elsternwick,[4] residential/boarding facilities (Glen Waverley),[5] three outdoor education sites (Mallana, Chum Creek, & Lochend),[6] a year 9 residential learning campus in Clunes[7] and the Yiramalay/Wesley Studio School (Yiramalay) in the Kimberley Region.

[10] Wesley College operates in a three mini-school structure (Junior, Middle & Senior Schools), which caters for students from early childhood through to Year 12.

Wesley enrolment is not subject to entrance examinations or other requirements[11] although some preference is given to female students in order to achieve gender balance.

Year 9 students spend eight weeks living with one another as part of a unique residential program, where they learn with and contribute to the local community.

[18] Girls and boys live separately in 15 residential houses designed by award-winning architect, Daryl Jackson AO.

[19] Established in 2010, Yiramalay was born out of a partnership between Wesley College and the Bunuba community of the Kimberley in Western Australia.

[21] Wesley's 130 hectare outdoor education camp at Chum Creek, near Healesville, commenced in 1952, coinciding with the establishment of Timbertop by Geelong Grammar School.

The original 200 acres (81 hectares) site was donated in 1952 by Alfred Wall, a parent whose family still owns land adjacent to the camp.

Camp Mallana is located on 5 hectares (12 acres) on the Banksia Peninsula, between Bairnsdale and Paynesville, with frontage to Lake Victoria and the Duck Arm shoreline.

[22] Lawyers accused the private school’s administration of allowing abuse to flourish and failing to protect students.

[22] A former student at Wesley College was awarded a record settlement of $3 million as compensation for institutional child abuse, after the court ruled that he was sexually assaulted by two former teachers at the school in the 1970s.

[26] Major benefactor Walter Powell encouraged other Wesleyan Methodists to bridge the gap in funds between the government grant and that required to build the school.

[32] The St Kilda Road campus was substantially rebuilt and expanded between 1933 and 1939 following a bequest from philanthropists Alfred and George Nicholas.

The school purchased land at Syndal in 1955, and for the next few years considered selling the St Kilda Road campus to fund building at its new location.

[42] However, by 1959 it had decided to retain its St Kilda Road location, move the Junior School and establish playing fields at Syndal.

The Adamson Theatre Company, named after its principal performance venue[63] was established by Tony Conabere at St Kilda Road campus in 1988.

[65] The Glen Waverley campus has performed in New Zealand, Hong Kong, Thailand, Japan, Canada, America, England, Ireland, France, Italy and Germany since 1987.

The Public Questions Society (PQS) was established at Wesley College in May 1924[70] and was instituted to provide a forum in which contemporary and controversial issues could be discussed.

[71] Past speakers have included: Bob Hawke, Dick Hamer, Neale Fraser, Al Grassby, Lou Richards, Keith Dunstan, Ivan Southall,[72] Geoffrey Blainey, Andrew Lemon and Wade Davis.

Wesley College and the City of Port Phillip are joint owners of the Albert Park Tennis and Hockey Centre,[74] a facility used by a number of schools, community groups and the general public.

[77] At the Clunes campus the internal works of the heritage-listed Wesleyan Church were completed in 2010 with new heritage walls, flooring, ceiling and lighting installed; the historic pipe organ was also refurbished and rebuilt.

The music school was completely rebuilt as a state-of-the-art music and drama facility and the adjacent Adamson Hall, the campus's primary dramatic theatre, was extensively refurbished with an expanded capacity of 580 seated, a fly tower, a hydraulic thrust stage, and a revamped sound and lighting rig.

[80] In 2007 Wesley introduced tablet styled notebook computers and was the first educational institution in Australia to do so[citation needed], but by 2010 were no longer being issued.

[81] Wesley introduced interactive whiteboards across all classrooms and some lecture theatres in 2008, allowing notes to be printed to a nearby printer or emailed to students.

[86] At the St Kilda Road campus, a joint venture with the college's neighbour, Deaf Children Australia, is in place to drill a bore and two 55,000 litre tanks have been installed.

In maintaining with the college's environmental commitment, the lawn will be a carbon neutral project with additional landscaping to be undertaken around the perimeter to maximize rain catchment.

To this end, a pilot vocational program is being considered within the cattle industry in northern Western Australia, as part of the partnership Wesley has with the community at Fitzroy River.

In April 2010, the Wesley College Institute hosted the 2010 Global Language Convention at Glen Waverley, with delegates attending from 17 universities and over 140 schools.

Wesley College's alumni include two former prime ministers, thirteen Rhodes scholars, five current supreme court judges and 36 Olympic athletes.

[91] Among the most notable Old Wesley Collegians are former Australian Prime Ministers Sir Robert Menzies and Harold Holt, historian Professor Geoffrey Blainey AC, cricketers Sam Loxton and Ian Johnson (both members of The Invincibles), AFL player and dual Brownlow Medallist Ivor Warne-Smith and politician, businessman and Olympian Sir Frank Beaurepaire, multiple Olympic and World Championship gold medallist Michael Klim, multiple world champion Emma Carney, tennis player Mark Philippoussis, netballer Sharelle McMahon and multiple knights of the realm.
