I fell in love with ODI cricket again during the recent Cricket World Cup, and it gave me the chance to compare the 50 over game with T20. The partnership between batters is more crucial in the fifty-over game, with Australia, India, and South Africa excelling in this aspect while England, Pakistan, and Bangladesh struggled. In this article, I will look at Australia’s best partnerships in different World Cups. Quality was given more importance than quantity, considering the match’s significance, the opposition bowling, and pitch condition. The 1st Wicket partnership of Adam Gilchrist and Mathew Hayden in 2007 is notable, along with the 2nd Wicket partnership of Aaron Finch and Steve Smith in 2015. The 3rd Wicket partnership of Ricky Ponting and Damien Martyn’s 234* versus India in 2003 was game-changing. Travis Head and Marnus Labuschagne’s 192-run 4th Wicket partnership against India in 2023 was also noteworthy. Stuart Law and Micheal Bevan’s 138-run partnership against WI in 1996 showed remarkable resilience. Similarly, Ross Edwards and Rod Marsh’s 99-run partnership in 1975 against WI was significant, as was Doug Walters and Gary Gilmour’s 45-run partnership against England in 1975.
