The first-ever One Day International (ODI) match was played between Australia and England on January 5, 1971, at the Melbourne Cricket Ground (MCG). The match was played after the first three days of a scheduled Test match were washed out due to rain, and it was decided to play a 40-over-per-side match (8-ball overs).
Australia won the match by 5 wickets, with England scoring 190 and Australia chasing it down with 42 balls to spare.
