Canon Morris based much of the school's ethos on its patron saint, St Magnus, a Norsemen earl known for his strength of character and his qualities as an educated Christian man. The Viking tradition is reflected in the school coat of arms, with its shield and battle axes symbolising Viking courage, and its crossed axes signifying self-sacrifice and St Magnus' martyrdom. Many of the school's rowing boats are named after Viking figures, and the school mascot, 'Eric', is also a Viking effigy.

In May 2004, Frederick Roy Hoskins, a former teacher and boarding house head, pleaded guilty to seven child sex offences committed against seven victims aged nine to fifteen between 1947 and 1955. The crimes occurred over a 10-year period at the school.

In October 2009, the deputy head of the preparatory school, Chris Klemm, who had worked at the school for almost three decades, was stood down due to 'serious allegations' made against him. The Headmaster issued letters to all parents regarding the matter, but kept the allegation, which was revealed in the mid-semester holiday break, confidential. In November 2010, Klemm was convicted of child sex offences and received a jail sentence of five years.

On 18 February 2023, a student pulled a knife at the Churchie rowing sheds after his 'bag of lollies went missing'. Police were called to the scene and the 14-year old boy was dealt with under the provisions of the Youth Justice Act.

On the afternoon of 7 December 2007, a fire started in the Lanskey Building between two Year 7 classrooms. The automated fire system set alarms off, and just after 4:30 pm the Queensland Fire and Rescue Service arrived to find two classrooms badly damaged.

During April 2008, there was community debate when students were disallowed from inviting male partners to the school formal. The school's Headmaster referred the matter to the School Council, which released a statement saying that it 'strongly supported the headmaster's position on the school's education programs in social settings'.

Churchie's twenty-two hectare campus is located in inner-city Brisbane. The school occupies the entire eastern side of Oaklands Parade, a street in East Brisbane, and extends all the way down to the banks of Norman Creek, a tributary of the Brisbane River. The first building on the site was the old boarding house, erected in 1918. Most of the school's buildings are built in the Gothic Scholastic style, characterised by 'decorative, half-timbered gables, red brick face-work, gargoyles and terracotta tiles'. Churchie has all of its sporting and cultural facilities on its East Brisbane campus—including ten playing fields, three swimming pools, two basketball courts, seven tennis courts and gymnasium—on the one campus. The Graham Fowles Boathouse is located approximately one kilometre away in Mowbray Park.

Notable buildings and facilities on the Churchie campus include:

• Morris Hall – Churchie's main social, cultural and musical building
• Magnus Hall and Magnus Quadrangle – the school's main academic building
• The Canon Jones Memorial Chapel – the spiritual centre of the school, named after Canon Thomas Jones, an early supporter of the school. Canon Morris' remains are interred under the chapel's altar
• Darnell – originally the school library, now the School Council Room and The Old Boys Room
• School House – the school's oldest building and boarding headquarters
• The Sir John Pidgeon Sports Complex – contains the school's basketball courts, volleyball courts and gymnasium
• The Hayward Midson Creative Precinct – home to Visual Art, Film and TV and Design and Technology faculties
• The Centenary Library – comprising the Senior School Library, Churchie IT, Student Services, Churchie Archives and museum, Mawson House, the Churchie Research Centre, Churchie Learning Support, The Arches café and various classrooms and multipurpose study spaces.
• The 'Pocket' – a triangle of land bordered by Norman Creek that contains six of the school's playing fields, including the Main Oval

Churchie provides a scholastic environment based on personalised academic pathways for every student developed through academic profiling and examination of each student's individual needs. The school's approach is strongly influenced by the values and writings of Canon Morris, the school's founder, who believed boys needed a clear sense of what was right – honesty, integrity, perseverance, patience, courage and courtesy.

Churchie is involved in a number of educational research programmes carried out by various Australian universities, including the universities of Melbourne and Swinburne University of Technology. Its new generation learning space and emotional intelligence programmes are examples of such research-led initiatives.

In 2017, Churchie was authorised by the International Baccalaureate Organisation as an IB World School for the delivery of the Diploma Programme and the Primary Years Programme.

Churchie's Preparatory School comprises Reception to Year 6. Students in Years 4, 5 and 6 must lease from the school their own tablet computer as part of Churchie's tablet computer programme. The subjects available to prep students are:

In 2015, Churchie combined the middle and senior schools into a single Senior School for the secondary school years (7 to 12). Students in Years 7 to 9 use the same curriculum, which focuses on English, mathematics, humanities, science, modern languages (Japanese, Mandarin, Spanish or French), religious education, and health and physical education. Electives include design technology, and visual and media arts, music, drama, geography, engineering technology, advanced science, information technology, film, television and new media and philosophy and critical reasoning. Year 10 is a preparatory year, in which subjects are presented (where possible) as precursors to what can be expected in Years 11 and 12. All subjects are assessed and reported under a criteria-based approach. Year 10 Students study English, mathematics, history, science, religious education, modern languages and history plus three elective subjects. In Years 11 and 12, students study six subjects. English and Mathematics A or Mathematics B are compulsory. The remaining four are drawn from the following list:

Students also receive leadership development training as part of the pastoral learning curriculum and the school's outdoor education programme. Senior students are able to apply their leadership skills during house and co-curricular activities by, for example, mentoring younger students or undertaking duties for the house or School.

Churchie offers a range of sporting and cultural activities to all students. The school is a member of the Great Public Schools (GPS) sporting competition and competes in most available sports. Boys of all skill levels are given the opportunity to participate in numerous sports, including: basketball, chess, cricket, cross-country, debating, football, rowing, rugby union, swimming, tennis, track and field, volleyball and water polo. Churchie has been highly successful in the GPS sporting competition winning the top GPS school premiership over all competitions 3 cosecutive years (2010, 2011 and 2012). This premiership was known as the Bauman Cup which was first awarded in 1953 and discontinued in 1977. Churchie was awarded the Bauman Cup a record 16 times.

Basketball

GPS school began competing in an annual basketball premiership since 1986. Since 1986 Churchie has won 8 outright premierships and 2 shared premierships. Churchie's latest premiership was in 2024. The team went undefeated.

Churchie's Premier Chess Team secured the GPS Chess Premiership for two consecutive years in 2018, 2019. Churchie has continued this success in 2024 by securing its fifth consecutive GPS Chess Premiership.

Churchie entered the GPS competition in 1922 and played the first match against Gregory Terrace on the 25 February 1922.

It wasn’t until 1929 that Churchie won its first premiership (shared with The Southport School). Churchie has won twenty premierships between 1922 and 2020. Churchie’s cricket programme has seen numerous successes over its long history, including a premiership win in 2012 after 13 years.

Churchie has also seen its winning percentage across all grades soar from 30 per cent in 2009 to as high as 65 per cent in more recent years. Four Churchie Old Boys have represented Australia—Peter Burge, the Archer brothers Ken and Ron, and Tony Dell.

Cross Country

GPS Cross Country competition began in 1971 when the schools began competing in an annual cross-country championship. Churchie has been the most successful school in GPS Cross Country based premierships with 15 outright premierships and 2 shared premierships. Churchie's most recent premiership was in 2012.

Junior Cross Country

GPS schools began competing in an annual Junior Cross Country carnival since 2014. Churchie has had high success in Junior Cross Country being the first school to win the inaugural GPS Championships event for Year 5-7 in 2014. Churchie has the second most premierships with 4, behind Nudgee College's 7. Churchie's most recent Junior Cross Country premiership was in 2023.

Churchie has won the GPS Debating Premiership competition three times since it commenced in 2002, winning in 2007, 2012 and 2020. Churchie's most recently premiership was in 2022.

In 2019, Churchie's First XI achieved the school's first-ever GPS Football premiership since the competition began in 1991. Churchie First XI most recent Football premiership was won in 2024.

Churchie's rowing history dates back to its establishment in 1912. Rowing was initially based at the Toowong Rowing Club, near the school's original grounds. Later, in 1917, the school built its own boatshed and rowing facilities at Norman Creek. Shortly after the opening of the Norman Creek boatshed, the school began a rowing competition between day and boarding students, held over a 5/8-mile course, which has been held sporadically since 1920. In 1936, the Elder Hunter boatshed was built on the banks of the Brisbane River in Mowbray Park, East Brisbane. The school's rowing program now operates from the Graham Fowles Boathouse, built in 2005 on the site of the old boatshed.

Since 1918, Churchie has entered both quads and eights in the Queensland Head of the River, Queensland's premier high school rowing competition. From 1918 to 1954, the O'Connor Cup for the Open 1st VIII race was contested in quads. Churchie won the cup six times in quads (1922, 1926, 1936, 1939, 1940 and 1941). Since the introduction of eights in 1955, Churchie has won ten times (1963, 1969, 1971, 1973, 1975, 1998, 2004, 2005, 2010 and 2012). The School has won the Old Boys' Cup, awarded to the school with the greatest number of points, a total of nine times (in 1990, 1991, 1999, 2004, 2005, 2006, 2019, 2020 and 2021) since the award's inception in 1988.

In 2012, the Open 1st VIII participated in the Princess Elizabeth Challenge Cup at the Henley Royal Regatta in the United Kingdom, the first Churchie crew to do so.

Initially, rugby league was played by the GPS schools; only in 1928 did they convert to rugby union. With seventeen premierships as of 2014, Churchie has always been one of the strongest schools in the rugby competition. Only Nudgee College has won the premiership a greater number of times. Churchie's 2005 undefeated premiership-winning 1st XV contained two future Australia players: David Pocock and Quade Cooper. Twenty-four Churchie students have been selected for the Australian Schoolboys national rugby union team, the highest level of schoolboy rugby in Australia, since the team's inception in 1973. In 2010, the school was identified as one of the 'nurseries of Australian schoolboy rugby' by the Australian Schools Rugby Union (ASRU). In all, sixteen Churchie boys have gone on to become Wallabies:

GPS Schools began competing in an annual swimming competition since 1918. Churchie won multiple swimming premierships with 21 outright premierships since the competition began. Churchie's most recent premiership was in 2014.

Junior Swimming

Junior GPS Swimming Championships began in 2014. Churchie won the Junior GPS Swimming Championships a total of four times (2014, 2015, 2020, 2021). Junior Swimmers range from 10 Years & Under to 12 Years & Under.

The first tennis captain was appointed in 1921 and tennis courts were built that same year.

These courts remained in service (with extensions and modifications) until 2009 when the Sir John Pidgeon Sports Complex was built on the site. Other courts were also established for a time behind School House.

Churchie now has 11 courts for the boys and community to use. In 2011 the David Turbayne Tennis Centre opened. It has seven fully-lit courts with Rebound Ace (rubber) surfaces. Churchie also has access to the council-owned Hazel Millman four tennis hard courts, which are located in Heath Park.

Churchie has won the GPS Tennis Premiership 11 times since the competition began in 1918.

Track and Field

Churchie held its first sports day at the Toowong Sports Ground in 1916, while the first sports day at East Brisbane took place in October 1918 on the newly-laid Main Oval. Although only 157 boys attended the School in 1918, this first sports day, with its combination of races, jumps and novelty events, set the pattern for the future, and the annual sports day became, for many years, a major sporting and social event in the School Calendar.

After the annual sports day, a team was selected to train for the All-Schools Sports. Before the GPS Association was established in 1918, the Queensland Secondary School Association (often called the All-Schools Sports), conducted fixtures for Brisbane schools. Track and Field began in 1918 and in 1923 Churchie won its first GPS Track and Field Premiership.  

In the 1940s Churchie took three more premierships before entering a golden age from 1952 to 1965 when the School won the premiership 13 times in 14 years, including 10 consecutive titles from 1956 to 1965, and again in 1973 and 1974, giving us a total of 20 premierships.

Schools have competed in an annual athletics competition since 2014. Churchie has won 2 premierships and is second behind Nudgee College.

Water Polo

Water polo began at Churchie in 1996, and in 1997, Churchie entered its first competition with five teams.

Churchie won the 2003 Southern Skies Open Championships and the 2012 Queensland Schools Tournament and was runner-up in the 2004 Tasman Cup Tournament, which featured entries from interstate and New Zealand.

Even though water polo is not a recognised GPS sport, in 2009, 2010 and 2017 the Open Firsts emerged as undefeated premiers in the Independent School Competition.

Churchie students who have represented Australia at various levels include William Armstrong, James Broadley, Tom Culleton, Michael Dance, Tim Dance, Nick Godfrey, Duncan Greenbank, Stewart Greenbank, Zac Hudson, Tyler Sinclair, Tom Woudwyk and Alex Yeates.

In 1994, volleyball became a GPS sport and Churchie fielded teams in the U13, U15 and Open divisions. The first GPS Volleyball Premiership won by Churchie was in 1998.

In 2022, Churchie Volleyball included 271 players across 29 teams from Years 7 through 12. Teams commence trials and pre-season games in Term 4 with the GPS Volleyball competition played through Term 1.

The Churchie First VI were GPS Premiers and holders of the Peter Donaldson Memorial Trophy in 1998, 2016, 2017, 2018 and 2020. From 2016 to 2018, the Churchie First VI remained undefeated for three consecutive years.

Most recently, Churchie has won back to back undefeated Volleyball Premierships (2023, 2024).

Gymnastics

Schools have competed in an annual gymnastics competition from 1915 to 2021. Churchie had won 16 outright premierships since 1915 to 2021 and is second behind Brisbane Grammar School. Churchie no longer consistently compete in gymnastics (occasionally, small teams/individuals have represented these schools at the championships). The GPS Gymnastics has been officially discontinued as a GPS sport after the 2020 GPS Championships, however the GPS Gymnastics Foundation Cup has been contested since 2021, where Churchie may compete.

Sailing

An annual sailing competition was instigated in the GPS in 2000. Churchie has had success in Sailing from 2000 to 2021, winning four times, Churchie has the third most wins behind Brisbane Grammar School and The Southport School. Sailing has been officially discontinued after the 2020 GPS Championships discontinued by the GPS Association. The GPS Sailing Foundation Cup has been contested since 2021.

The school's music program includes a symphony orchestra, an assortment of bands and choirs and a choral dectet. Individual tuition is available for students studying an instrument or voice and speech. Churchie also provides the choristers for St John's Cathedral.

In July 2000, the Churchie Symphony Orchestra performed the prelude music and the national anthem at A Service for Australia in Westminster Abbey, London, to commemorate the Federation of Australia.

Churchie runs annual musicals in conjunction with Somerville House. Productions have included Peter Pan (2017), Grease (2016), Alice in Wonderland (2015), How to Succeed in Business Without Really Trying (2014), The Sound of Music (2013), Oliver! (2012) and Charlie And The Chocolate Factory" (2024). The Stage Crew is a group of school students who work on productions, assemblies, service events, dances and other activities that require technical organisation.

Each year, the school showcases the work of its Film, TV and New Media students at the Churchie Awards in Media (CAM). Similarly, Visual Art students display their work at CART, the Churchie Art showcase.

The churchie national emerging art prize was established in 1987 as an initiative of the school. From 2010 until 2019, the school had a partnership with the Griffith University Art Gallery at the Queensland College of Art, with staff members from the school sitting on the committee as well as developing educational materials to complement the exhibition of finalists, aimed at school-age students as of 2013.

Since 2019 and as of 2022, the Institute of Modern Art in Brisbane has hosted the awards.

Community service, along with scholastic attainment, spiritual awareness and personal growth, is one of the four tenets of the school. Churchie students are regularly involved in a number of charitable events including doorknocks, fundraisers (especially for the Leukaemia Foundation's World's Greatest Shave), nursing home visits and mobile Blood Bank donations. The school also conducts international service tours where students assist local schools and community organisations. Recent international service tours have visited India, China, Vanuatu and Samoa. On the final day of Term two, a Prep School Billy Cart Race is held to support World Vision. One of the most important service activities for the year is the Sony Foundation Children's Holiday Camp Program, where students from Years Eleven and Twelve care for a child with special needs during the September Holidays. In 2012, Churchie won the Queensland Community Foundation's Corporate Community Philanthropist of the Year Award for donating over $2 million over the past two decades to charitable foundations.

As with most Australian schools, Churchie uses a house system. Each student is a member of one of its eleven houses, and competes in inter-house events. Churchie's inter-house competition includes swimming, cross-country, track and field, trivia, lightning chess and singing. Points are awarded based on a house's participation and position. In addition to the Inter-House Cup awarded at the end of the year, shields are awarded to the house that comes first in each event. Canon Morris started Churchie's house system in 1935.

Day students from the middle and senior schools belong to one of nine-day houses. (The preparatory school has four houses, all of which are day houses: Jutes, Angles, Saxons and Danes.)

Biggs

Biggs house was named after E.E. Biggs, a member of the first school council. He attended the school from 1918 to 1923. The Biggs family's association with the school continues to the present day. The house motto is Semper Conemur ("Always Striving"). Colours: blue and white.

Casey

Casey house was founded in 1971 and named in honour of Richard Gardiner Casey (1890–1976), later Baron Casey of Berwick, a distinguished Australian diplomat, politician and Governor-General of Australia. The house motto, Vis et Unitas, is usually translated as "Progress Through Unity". The house coat of arms incorporates themes from Casey's own coat of arms, with the addition of the crossed Viking swords. Colours: gold and royal purple (Baron Casey's own colours).

Grenfell

Grenfell, founded in 1935, was one of the first four-day houses at Churchie. It was named after Sir Wilfred Thomasson Grenfell, who was born at Parkgate, England, in 1865. Grenfell was a doctor whose love of the sea and interest in boating led him to becoming a master mariner. A lecturer of his suggested he join a large fishing fleet as their doctor. Within five years he had encouraged the fishermen to stop drinking alcohol and Queen Victoria's interest in his successful persuasion of the crew led to her presenting the fleet with its first hospital boat. In 1891, Grenfell sailed to Cape St. John in the North Atlantic. He was mobbed by people who needed medical attention. The following spring he returned to Labrador with two doctors and nurses, where he set up two hospital bases for the Eskimos who populated Labrador. A third hospital was set up at St. Anthony in about 1898. Sir Wilfred Grenfell gave the school permission to use his personal motto, Loyal Devoir, and coat of arms when the house was established. Colours: red and gold.

Hillary

Hillary house was named by the late headmaster Charles Fisher, who looked for men who had achieved success in their chosen field. He chose Sir Edmund Hillary, who, in 1953, was one of the first men ever to climb Mount Everest. The house colours and crest were chosen by the first students of Hillary from designs submitted by students. The crest incorporated the symbols of knighthood—a knight's helmet, a castle, and a fist pointing upward. The house motto is Semper Sursum ("Ever Upward"). Colours: black and gold.

Kingsley

Kingsley was one of the original four houses. It held both day and boarding students until 1950, when the two boarding houses were created. In 1971, Kingsley House was divided to create Biggs and Hillary houses. Canon Morris chose Charles Kingsley, a man he considered a Christian with a Viking's courage, as the house's patron. History revealed Charles Kingsley to have been a man who practiced his Christian beliefs and followed his social conscience to help the less fortunate, with whom he chose to live. The Kingsley house motto, Age Quod Agis, translates loosely as "Do What You Do Well". Colours: black and white.

Magnus

Magnus was one of the original four-day houses. The house is named after St Magnus, Churchie's patron saint. The house's coat of arms is a simple shield with St. Magnus holding a sword and a palm of martyrdom. This image of St Magnus is from a stained-glass window in St Magnus Cathedral in Orkney and dates back probably to the thirteenth century. The house motto is Sibi Fidelis ("Be Faithful To Oneself"). Colours: maroon and royal blue.

Mansfield

Mansfield was named after Sir Alan Mansfield, a distinguished barrister and former judge, Chief Justice and Governor of Queensland. Sir Alan attended the school when it was known as St. Magnus Hall. The house crest borrows heavily from the Mansfield family coat of arms. The house motto is "Steadfast". Colours: white and blue.

Mawson

Mawson house was named after Sir Douglas Mawson, a distinguished geologist and Antarctic explorer, who became famous for his discovery of the South Magnetic Pole in 1908 and his ill-fated second journey to Antarctica in 1911. He continued to visit and explore Antarctica up until 1931. The house motto is Alis Austri ("On the Wings of the South Wind"). The Mawson coat of arms includes the vessel Mawson used on his voyages south and the Southern Cross. Colours: red and green.

Nansen

Nansen was one of the original four houses, named after Fridtjof Nansen, a scientist, explorer and humanitarian. The Nansen house crest was established at Churchie in 1938; inscribed on the crest is the motto Fram, which means "Forward". Colours: green and white.

There are two boarding houses, both based on the school grounds.

Gerald

Gerald house was opened in 1934, as the need for new boarding accommodation grew. Prior to 1959, boarders took part in competitive sport as members of a day house. This changed in 1950, when the boarding houses became sporting competitors in their own right. The house was named after Gerald Sharp, Archbishop of Brisbane (1921–1933). The house crest shows the Bishop's mitre which symbolises the connection with Archbishop Sharp; the large star signifies God; the two smaller stars king and country, and the five small stars signify truth, honesty, duty, comradeship, and charity. The house's motto is Fideliter Et Constanter, meaning "Faithfully and Constantly". Colours: green and yellow.

Goodwin

Goodwin house was opened in 1928, and named after Lieutenant General Sir John Goodwin, most famous for his medical work in World War I. Goodwin took interest in the progress of the school while he was Governor of Queensland. The house motto is Fide et Virtute, meaning "By Faith and Courage". The Goodwin house crest is the family crest of Sir John Goodwin, who suggested it be adopted by the house when he granted permission for it to be named Goodwin. Colours: red and gold.

In 2006, Churchie lessened the number of school houses in the inter-house competition. Five houses—three-day and two boarding—were abolished, reducing the total number of houses from sixteen to eleven. The three-day houses removed were Alban (dark blue and sky blue), Schonell (red and blue) and Halse (gold and light green). Donaldson (blue and gold) and Strong (gold and black) are the two former boarding houses.

A number of student and leadership groups exist at the school. The Prefect Body is a group of seniors selected by the students and teachers of the school to lead the student body in all aspects of Churchie life. It is led by the three school vice-captains and the School Captain, who are collectively known as the Student Executive. The Head Boarder is the leader of the boarding students. The Student Council is a student organisation, led by the Speaker of the House (a school vice-captain) and the two managers-of-business, consisting of the assembly and the cabinet. Service Coordinators is a group of seniors selected within their houses and led by the President of Service who encourage service within the school.

Since 2008, boys in Year Nine must participate either in weekly community service, scouting or the Tri-Service Cadets program. Boys must commit to these until the end of Year Nine. The school also operates the Duke of Edinburgh's Awards and in November 2014, Prince Edward, accompanied by Governor of Queensland Paul de Jersey, visited the school to promote the award as part of an Australian tour.
