Mitchell Johnson made a significant impact on the international cricket stage with his Test debut in November 2007 against Sri Lanka, taking 4/96. Prior to this, he had made his ODI debut in December 2005 against New Zealand and his T20 debut in September 2007 against Zimbabwe. Known for his left-arm fast bowling, Johnson quickly established himself, notably taking 8/61 against South Africa in 2008. He also demonstrated his all-round capabilities with the bat, scoring an unbeaten 96 and later 123 not out, both against South Africa in 2009.

Later in 2017, Johnson delivered a pivotal last over in an Indian Premier League (IPL) final, directly contributing to another championship title for his team. His ability to deliver under pressure across various global leagues underscores his enduring value as a high-performance athlete.
