Since the first two years the format has only been adhered to once (in 2004, even though respectively in 2010 and 2016 there was a Test Series in Australia and an Autumn International in England), World Cup matches are not counted.

In 2022, ahead of England's 3-test series tour to Australia, the Cook Cup was retired in favour of a new trophy that better represented both countries.

Designed by aboriginal artist Natalie Bateman, the trophy incorporates mullet, song lines and indigenous battle symbols for Mark Ella, while Edgar Mobbs is represented with the English rose, a fox, footsteps and the Northampton castle symbol he wore on his lapel in battle.

Two years later the Wallabies broke the trend when the magnificent Grand Slam team of 1984 won away from home at Twickenham by 19–3.

The series was decided through two tests, and with the second match at Twickenham resulting in a 15–15 draw, Australia were crowned champions.

In 1998, Australia ran out record 76–0 winners at Lang Park in Brisbane, playing a severely depleted England side.

The subsequent meeting at Twickenham in December was a much closer affair, with Australia winning 12–11 thanks to a late Eales penalty.

In 2000, England won the Cook Cup for the first time, beating Australia 22–19 at Twickenham with an injury-time try by Dan Luger.

Jonny Wilkinson landed a drop goal in extra time that saw England win 20–17 to claim their first Rugby World Cup.

The 2004 Cook Cup was contested over two matches, Australia winning 51–15 at Brisbane in June and 21–19 at Twickenham in November.

In November 2017, England retained the cup with a 30–6 win, and on 24 November 2018 England held onto the Cup with a 37–18 victory, and in doing so, set a longest winning streak of six matches in a row for rugby internationals between these two nations.
