The Fourth Test of the 1948 Ashes series was one of five Tests in a cricket series between Australia and England. The match was played at Headingley Cricket Ground at Leeds from 22 to 27 July with a rest day on 25 July. Australia won the match by seven wickets to take an unassailable 3–0 series lead. In successfully chasing a target of 404, they set a new world record for the highest victorious runchase in Test history, a record lasting until 1976.

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. Australia are the current ICC World Test Championship and ICC Cricket World Cup champions. They are regarded as most successful cricket teams in the history of Cricket.
