The Australia national rugby union team is the national team of Australia in the sport of rugby union and represents the country in all men's international matches (test matches). It is usually referred to as the Wallabies. This term refers to several species in the kangaroo family, which in turn are the country's national animals. For marketing reasons, the national team is referred to at official level as the Qantas Wallabies.

The team's most important international appearances come at the quadrennial World Cup. The Wallabies have competed every time since their inception in 1987 and are the third most successful team in the tournament with two titles, behind New Zealand and South Africa, who have won three titles each. The Wallabies won the 1991 World Cup final against England and the 1999 World Cup final against France. Australia also reached the finals of the 2003 World Cup and the 2015 World Cup, losing to England and New Zealand respectively.

Since 1996, the Wallabies have participated in the annual Rugby Championship tournament (known as the Tri Nations until 2011). Participants are the four best national teams in the southern hemisphere: the Pumas from Argentina, the All Blacks from New Zealand, the Springboks from South Africa and the Wallabies. The Rugby Championship will see the Wallabies play Argentina for the Puma Trophy, New Zealand for the Bledisloe Cup and South Africa for the Mandela Challenge Plate. The Wallabies have won the Tri Nations three times (2000, 2001 and 2011), and the Rugby Championship for the first time in 2015.

The Wallabies played their first international match in 1899, when Australia took on the British Lions. The central governing body for the Wallabies is Rugby Australia, which is part of the first tier of World Rugby, along with ten others. The national team wears the country's traditional sporting colours of green and gold at both their home and away matches. In 2001, World Rugby awarded them "Team of the Year". 14 former players have been inducted into the World Rugby Hall of Fame.
