The club was actually founded in 1902 as Union Football Club (not to be confused with the defunct Unions club from Fremantle) and competed in the Perth Third Rate Association Competition (however an earlier 'East Perth' had formed in 1891). The club was successful and was promoted to the First Rate Association. After continuing to succeed at this level they applied to join the WAFL and hence became a member in April 1906. The club became known as East Perth in accordance with the WAFL's policy of having each club represent a district in Perth. After a relatively slow start – despite being competitive from its first season – East Perth after
World War I went on to become one of the most powerful clubs in the West Australian league with the appointment of former Subiaco player
Phil Matson as captain-coach. The club won five consecutive WAFL premierships between 1919 and 1923, and after a brief lapse due to Matson's death in a truck crash recovered to contest the finals every year from 1931 to 1940, but won only one premiership – a frustrating record to be repeated in the 1970s. Although the club garnered an undefeated premiership in the under-age WAFL competition in 1944, East Perth became very much a middle-of-the-road side after open-age WANFL football resumed until the emergence of champion ruckman
Graham "Polly" Farmer in 1956. That year, despite being held to the lowest WAFL score between 1946 and 2002 by Perth in torrential rain and genuine darkness at the WACA, the Royals won fourteen of their nineteen games and beat
South Fremantle twice in the finals. Under the coaching of Jack Sheedy, and aided by becoming the first WAFL club to pay players formally, the club contested the following five grand finals for further premierships in 1958 and 1959 and a huge upset loss to
Swan Districts in 1961. The loss of Farmer, however, saw a decline in fortunes: in 1964 the club won only one of its first eighteen games and finished with its first wooden spoon since 1929, but with the recruitment of
Kevin Murray the club returned to the top quickly. It returned to the finals in 1966 and played therein during every one of the next seventeen seasons except 1974. During these years East Perth won 246 and drew one of 388 games for a success rate of 63.5 percent: clearly the highest in a competition that – at least during the first half of this period – was extremely even and characterised by very rapid fluctuations in teams' fortunes. By 1980, the club had made a submission to enter the
VFL/AFL, however this was withdrawn, and from 1983 their fortunes declined abruptly: between 1985 and 1995 East Perth won only eighty and draw one of 235 games for a success rate of 34.26%. Indeed, between 1985 and 1989, the Royals actually won just 24 of 105 games for a success rate of 22.8% and did not finish above sixth, with a lowlight being the sacking of coach Greg Brehaut on 13 May 1986 that was followed by a walk-out of three managers from a reserves team that had won five matches out of seven. In 1996 the Royals returned to prominence and took the minor premiership before losing narrowly to Claremont in its first grand final since 1978. However, the club returned to the lower reaches of the ladder in 1999, winning only five of twenty games. East Perth later acted as the host club for
West Coast Eagles players recruited from interstate from 2000 to 2001 until the host club arrangement was abolished. This made them favoured for high honours in 2000 – which was achieved with five Eagles in the grand final side, though the Royals' "old guard" made a much larger contribution than expected to the club's first flag for twenty-two years. It repeated the dose emphatically in 2001, holding
South Fremantle to 0.3 (3) after half time, and yet again in 2002, but fell off steadily in the following four seasons to win only six games in 2005. A partial recovery in 2007 saw the Royals finish fourth, but it returned to last in 2008 before again rebounding in 2009 to finish fifth. Its first home ground was
Wellington Square. It then moved to
Perth Oval between 1910 and 2002, although it played games at the WACA from 1988 to 1989. East Perth began playing its games at
Leederville Oval from 2000, formerly the home of bitter rivals
West Perth), but the club only officially moved there in 2003. They have since been joined at the ground by the
Subiaco Football Club. East Perth finished runners up in the 2025 WAFL Grand Final, narrowly losing to South Fremantle. The final whistle was considered by some as somewhat controversial as East Perth were awarded a free kick in the centre of the field but were correctly not awarded a 50m penalty. ==Current squad==
