The England national cricket team toured Australia from November 1979 to February 1980 and played a three-match Test series against the Australia national cricket team.
England were captained by Mike Brearley; Australia by Greg Chappell.
The first test was known for the ComBat incident, where Australian Dennis Lillee circumvented the Laws of cricket at the time by using an aluminium bat.
The two Test series overlapped, with Australia alternating between playing the West Indies and England.
This format was not repeated in subsequent years when two teams toured Australia in the same season, where one series would be completed before the next began.
