David Andrew Warner was born at Paddington, a suburb in eastern Sydney, New South Wales. At the age of 13 he was asked by his coach to switch to right-handed batting because he kept hitting the ball in the air. However one season later his mother, Sheila Warner (née Orange), encouraged him to return to batting left-handed and he broke the U/16's run scoring record for the Sydney Coastal Cricket Club. He then made his first grade debut for the Eastern Suburbs club at the age of 15 and later toured Sri Lanka with the Australian under-19s and earned a rookie contract with the state team. He has been seen practising hitting right-handed in 2016, which he had hit at least one switch-hit in all forms of the game.
Warner attended Matraville Public School and Randwick Boys High School.
Warner's breakthrough innings for the New South Wales Blues came against Tasmania when he smashed 165* to record the highest one day score by a Blues player ever. Warner later backed this up with a 54-ball 97 also against Tasmania to narrowly miss the record for the fastest ever century in Australian domestic cricket.
This introduction to the domestic scene led to Warner being included in Australia's Twenty20 squad in January 2009.
Warner finally made his first-class debut playing for New South Wales against Western Australia in the final match of the 2008–09 Sheffield Shield competition at the Sydney Cricket Ground on 5–8 March 2009.

While playing for New South Wales, Warner broke the record for the highest Australian one-day domestic score. His score of 197 came off just 141 balls and included 20 fours and 10 sixes, surpassing Jimmy Maher's previous record of 187.
Warner has played for English County Champions Durham for the English cricket domestic season.
David Warner has been one of the most successful batsmen in the Indian Premier League. He currently captains the Sunrisers Hyderabad, and plays a pivotal role at the top of the order.

Warner made his international debut for Australia in a Twenty20 International against South Africa at the Melbourne Cricket Ground on 11 January 2009. Warner’s international career started in 2009 with a bit of history – he was the first man since 1877 to represent Australia without a first-class match to his name. He made an immediate impact, scoring 89 off 43 balls with 7 fours and 6 sixes, including the then second-fastest fifty in Twenty20 International history. Warner was just 11 runs short of becoming only the second player after Chris Gayle to score a Twenty20 International century. His 89 was the second highest score on Twenty20 international debut; and the equal fifth highest score ever in Twenty20 internationals.
On 23 February 2010, playing a Twenty20 international against the West Indies at the Sydney Cricket Ground, he made a stunning 67 off just 29 balls.

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. During the one-day series in England, bowler Steve Finn hit Warner's thumb, breaking it. This meant Warner took no part in the rest of the series and the scheduled series to Bangladesh which didn't take place due to security issues.
Warner also became the first batsman to ever score three centuries at The WACA, with his top 2 scores in Tests both achieved in the same stadium. His top score of 253 was also the second-highest individual score to be surpassed by an opposition batsman in the same Test match, which was surpassed during Ross Taylor's knock of 290.
On 7 November 2015, Warner became only the third batsman in history of Test cricket to score centuries in both innings of a Test match thrice, after Sunil Gavaskar and Ricky Ponting. In the very next Test match against New Zealand, he scored his maiden Test double century at The WACA, Perth, his fourth consecutive century against New Zealand. In that same match, Warner also became the second opener in Test cricket history, after India's Sunil Gavaskar, to score three consecutive Test hundreds twice in his career, and the only Australian since Adam Gilchrist to score three consecutive hundreds (a feat Warner had done twice in just 13 months), while completing his 4,000 Test career runs as the 4th fastest Aussie batsman, the top three being the legendary Don Bradman, Matthew Hayden and Neil Harvey respectively.

In 2016, Warner had a reversal of form, scoring more runs in ODIs than Tests. Nevertheless, he still scored his 5,000th Test run and 3,000th home Test run against Pakistan on 28 December 2016.
On 3 January 2017, while playing against Pakistan at the Sydney Cricket Ground, he became only the fifth cricketer to score a century before lunch on the first day of a Test match, after Victor Trumper, Charlie Macartney, Don Bradman and Majid Khan. Of the five, he was the first to do so in Australia. In Australia's second innings, with the team in need of quick runs, Warner clobbered a half century in a rapid 23 deliveries, making it the second fastest Test fifty of all time and the fastest by an Australian In the format. In the scheduled five ODIs against Pakistan, Warner progressed in a slow start but made two centuries in the final two ODIs at Sydney and Adelaide. At the 2017 Allan Border Awards, he was awarded Australia's ODI Player of the year and the elusive AB Medal. His two centuries made him man of the series and in the following days, he ascended to the top of the ICC ODI Player Batting Rankings – marking his ascent to the top of ODI rankings his first. He was later rested for the Chappell–Hadlee Trophy series in New Zealand and will join the second group of players in Dubai in preparation for the upcoming four-test series in India.

Warner is known for favouring the aerial route with his aggressive left-handed batting style, and ability to switch hit, using the back of his bat or by taking a right-handed stance. He is an athletic fielder and also a part-time spin bowler. His bowling style is rare in that he mixes off-spin bowling with his more usual leg-spin bowling. At just 170 cm Warner generates his power from strong forearms and uses his low centre of gravity to get underneath deliveries and hit them high in the air. In a Twenty20 match for New South Wales in 2009, he hooked a six off Shaun Tait that landed on the roof of the Adelaide Oval, only a month after hooking the same bowler 20 rows back at the SCG.
Former New Zealand captain Martin Crowe has called for a yellow-card and red-card system to be introduced to international cricket to curb Warner's "thuggish" on-field behaviour, stating that Warner was "the most juvenile cricketer I have seen on a cricket field".
On 12 June 2013, Warner was dropped for Australia's second match in 2013 ICC Champions Trophy match against New Zealand following an attack on an England cricketer. It later emerged that this player was Joe Root. The event happened hours after Saturday's loss to England at Edgbaston earlier that day. According to the sports journalist Pat Murphy, the incident took place at 2am at the Walkabout bar in the centre of Birmingham, UK. On 13 June 2013, the Australian Cricket Team 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. Warner subsequently missed the rest of the 2013 ICC Champions Trophy and the tour matches against Somerset and Worcestershire.
Warner attracted further controversy soon after. On 27 July 2013, whilst playing for Australia A against South Africa A in Pretoria he was involved in an on-field altercation with South Africa A wicket-keeper Thami Tsolekile. 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". Despite this, writers called into question his return to the Australia squad for the third Ashes Test against England, which seemed likely after scoring 193 in the first innings of this match. He was eventually recalled.
Warner married Australian ironwoman Candice Falzon in April 2015. They had their first child on 11 September 2014, a daughter named Ivy Mae Warner, and a second daughter, Indi Rae, on 14 January 2016. Warner was named Australian Sports Dad of the Year in 2016. Warner, one among ten nominees for the award, got to choose a charity to which AUD 10,000 would be donated.
