The Australia men's national cricket team represents Australia in men's international cricket. As the joint oldest team in Test cricket history, playing in the first ever Test match in 1877, the team also plays One-Day International (ODI) and Twenty20 International (T20I) cricket, participating in both the first ODI, against England in the 1970–71 season and the first T20I, against New Zealand in the 2004–05 season, winning both games. The team draws its players from teams playing in the Australian domestic competitions – the Sheffield Shield, the Australian domestic limited-overs cricket tournament and the Big Bash League.

The national team has played 853 Test matches, winning 405, losing 229, drawing 217 and tying 2. As of May 2022, Australia is ranked first in the ICC Test Championship on 128 rating points. Australia is the most successful team in Test cricket history, in terms of overall wins, win–loss ratio and wins percentage.

Test rivalries include The Ashes (with England), the Border–Gavaskar Trophy (with India), the Frank Worrell Trophy (with the West Indies), the Trans-Tasman Trophy (with New Zealand), and with South Africa.
