January — New Zealand plays its inaugural Test match, losing to England at Christchurch by eight wickets. England goes on to win the series 1–0 with three matches drawn.
Having scored 1586 runs in the 1929–30 Australian season at an average of 113.28 and including a world record individual innings of 452*, Don Bradman continues in the same vein through the Australian tour of England in 1930. Australia regains The Ashes, winning the Test series by 2–1 with two matches drawn. Bradman, with 974 runs in the series (still a world record), is the main difference between two strong teams.
