David Andrew Warner (born 27 October 1986) is an Australian former international cricketer and captain of Big Bash League team, Sydney Thunder.

In March 2018, following a preliminary investigation into ball tampering by the Australian team in the third match of their Test series against South Africa, Warner was suspended and charged with bringing the game into disrepute.

On 25 June 2024, Warner announced his retirement from international cricket after Australia's exit from the 2024 ICC Men's T20 World Cup.

However his mother, Lorraine Warner (née Orange), encouraged him to return to batting left-handed and he broke the under-16's run-scoring record for the Sydney Coastal Cricket Club.

[6] He then made his first grade debut for the Eastern Suburbs club at the age of 15[6] and later toured Sri Lanka with the Australian under-19s and earned a rookie contract with the state team.

[9] On 29 November 2008, Warner hit his first domestic One Day century for New South Wales with a score of 165* against Tasmania at Hurstville Oval in Sydney.

[11] Warner made his first-class debut playing for New South Wales against Western Australia in the final match of the 2008–09 Sheffield Shield season at the Sydney Cricket Ground on 5–8 March 2009.

[14] In the first season of the newly revamped Big Bash League, Warner was named as captain for the Sydney Thunder and scored 102 not out from 51 balls in his first match for the team.

[46] In 2018 he captained Winnipeg Hawks in the first season of the Global T20 Canada tournament[47][48][49] and in 2019 played in the Bangladesh Premier League for Sylhet Sixers.

In November 2023, David Warner was rumored to join Lahore Qalandars with his inclusion in the 2024 Pakistan Super League draft.

Despite not registering a century, Warner scored 418 runs during the series, the fourth highest run-scorer behind Steve Smith, Chris Rogers and Joe Root.

[100] Cricket Australia launched a separate investigation into the incident as a matter of urgency, led by Executive general manager Team Performance Pat Howard, along with Senior Legal Counsel and Head of Integrity Iain Roy.

[103] On 27 March 2018, before the findings of that investigation were handed down, specialist opening batter Matt Renshaw was urgently recalled to the squad from Australia for the Fourth Test.

On 27 March 2018, Sutherland announced that as a result of the preliminary investigation Smith, Warner and Bancroft had been charged with bringing the game into disrepute, suspended and sent home.

[104] Warner was found to be responsible for the development of the plan to alter the condition of the ball and instructing Bancroft on how to do it, including demonstrating the technique to him.

On 28 March 2018, they announced that they had decided not to continue their commercial relationship with him in light of the recent controversial events and dropped him as the brand ambassador of the LG Electronic Company.

[106][107] Later that day, Warner's contract with Asics was terminated; the company announced that it was a result of the prior weekend's events in Cape Town and following the sanctions made by Cricket Australia.

[113][114] In April 2018, Surrey head coach and former Australian cricketer Michael Di Venuto stated that he would be open to David Warner and Steven Smith playing for his county team.

[131] On 16 July 2020, Warner was named in a 26-man preliminary squad of players to begin training ahead of a possible tour to England following the COVID-19 pandemic.

Warner was included in the ODI, T20I and Test squads for India's tour of Australia taking place from November 2020 to January 2021.

[144] He entered the T20 World Cup following a disappointing IPL season with Sunrisers Hyderabad, however he quickly turned around his form around and went on to play a crucial role for Australia in the tournament.

[164] In the semi-final against South Africa, he became the third batsman after Rohit Sharma and Sachin Tendulkar to complete 500 runs twice in World Cup tournaments.

[165] In the final, he missed out with the bat scoring 7 off 3 balls but put in a strong fielding display as Australia beat India to clinch their sixth World Cup title with Warner winning his second.

[173] During the T20I series against the West Indies, at the post-match presentation ceremony of the third and last T20I, Warner confirmed his retirement plan from international cricket after the 2024 T20 World Cup.

At 170 cm in stature, Warner generates his batting power from strong forearms and his low centre of gravity allows him to get underneath deliveries and hit them high in the air.

On 13 June 2013, Cricket Australia announced that Warner was to be fined £7,000 (AU $11,500) and would not play for his country until the first Ashes Test on 10 July 2013.

This was deemed serious enough for the umpires to step in twice; however, no formal complaints were made and Warner tweeted later in the day describing it as "friendly banter".

[187] On 4 March 2018, during tea in the 1st Test in Durban, Warner was involved in an altercation with South African Wicket-keeper Quinton de Kock.

[189] Warner was charged with a Level 2 Offence and bringing the game to disrepute by the International Cricket Council and was given three demerit points and was fined 75% of his match fee.

[190][191] On 22 March 2018, after being dismissed in the first innings of the Third Test of that series held in Cape Town, Warner responded to baiting from a spectator which escalated into an unsavoury heated exchange as he walked to the dressing room.
