The Australia national rugby union team, nicknamed the Wallabies, is the representative national team in the sport of rugby union for the nation of Australia. The team first played at Sydney in 1899, winning their first test match against the touring British Isles team.

The British & Irish Lions is a rugby union team selected from players eligible for the national teams of England, Ireland, Scotland, and Wales. The Lions are a test side and most often select players who have already played for their national team, although they can pick uncapped players who are eligible for any of the four unions. The team tours every four years, with these rotating between Australia, New Zealand and South Africa in order. The most recent test series, the 2021 series against South Africa, was won 2–1 by South Africa.
