Rugby union in the Australian Capital Territory

[7] The first match of the 1899 British Lions tour was held at the Goulburn Showgrounds, and the Central Southern RFU put up a strong showing before the visitors prevailed 11–3.

[18] Royal Military College played a series of matches that year against the newly-formed Canberra Rugby Union Club instead.

[27] No rugby union matches were played in Canberra for the five years prior to 1936,[28] in the period when the Royal Military College was forced to relocate to the Victoria Barracks, Sydney due to the economic downturn caused by the Great Depression.

[29] After returning to Duntroon, the Military College played a re-formed Canberra Rugby Club in 1937, ten years after the teams had first met.

[40] In 1975 the ACT team won promotion to top division of the Wallaby Trophy, Australia's provincial championship at the time.

[42][43] In 1978, the ACT defeated the reigning Five Nations champions Wales at Manuka Oval, showing that they could compete with some of the world's best players.

[44] After the ACT team had comprehensively beaten New South Wales in 1994,[45][34] an invitation was issued for a Canberra club to play in the NSWRU Premiership for the following season.

The Brumbies play in the Super Rugby competition against other professional teams from Australia, New Zealand, South Africa,[49] and now also Argentina and Japan.
