In June 2016, England played a three-test series against Australia as part of the 2016 mid-year rugby union tests. They played the Wallabies across the three weeks of the June International window, 11 June–25 June, and contested the Cook Cup, which England had previously won eight times to Australia's twelve. The series was part of the fourth year of the global rugby calendar established by the International Rugby Board, which runs through to 2019.
England won all three matches—the first time it had won a test series in Australia. After defeating the hosts in the second match, England retained the Cook Cup and achieved second place in the World Rugby Rankings, demoting Australia to fourth. Australia had not lost every match in a home series since being "whitewashed" by South Africa in 1971.
On 12 June, Matt Toomua joined the squad as un-listed member of the squad after recovering from his knee surgery. Liam Gill also joined the squad after David Pocock was ruled out of the rest of the series.
On 20 June, Ben McCalman was ruled out of the last test of the series due to injury and was replaced by Leroy Houston in the squad.
On 23 June, Adam Coleman was named in an extended match-day 23 for the final test, despite not being in the initial 33-man squad.
