Context: The Australian cricket team toured Sri Lanka from 6 August to 20 September 2011.  The tour consisted of two Twenty20 Internationals (T20Is), five One Day Internationals (ODIs) and three Tests played for Warne-Muralidaran Trophy.  Four uncapped players had been named in the Australian Test squad; Shaun Marsh, Trent Copeland, James Pattinson and Nathan Lyon.  Lyon had only made four first-class appearances and was previously one of the groundstaff at the Adelaide Oval. This is a list of all men, boys and women who have captained a Sri Lankan national cricket team at official international level.  Sri Lanka became a full member of the International Cricket Council on 21 July 1981.  Previously they were an associate member of the ICC from 1965, which made them eligible to compete in the ICC Trophy, the leading one-day tournament for associate members.  Just after Sri Lanka gained Test status in 1981 a team of rebel players toured apartheid South Africa under the banner "Arosa Sri Lanka" (the term "Arosa" being derived from the promoter's name).  All players who toured Sri Lanka were banned from official cricket matches for life, thereby setting Sri Lanka's development back.  Sri Lanka's greatest success in One Day Internationals was when they won the Cricket World Cup in 1996 under the captaincy of Arjuna Ranatunga. The Bangladeshi cricket team toured Sri Lanka for three One Day International cricket matches and two Test cricket matches in August and September 2005.  The Bangladeshi team is coming off a moderately successful tour of England, by their standards, as they pushed Australia close in one ODI and beat them in another.  However, they still lost five out of six matches in the NatWest Series, and both of the Test matches, and remain at the bottom of both the ICC Test Championship and ICC ODI Championship.  The hosts Sri Lanka, meanwhile, are undefeated in home ODI tournaments since February 2004, and in home Test series since March 2004, both against the top-ranked Australia.  Their win in the Indian Oil Cup a month before this series saw them into second place in the ODI Championship, but they are only ranked sixth in Tests. Shaun Edward Marsh (born 9 July 1983) is an Australian cricketer who plays for the Western Warriors in Australian domestic cricket and has represented Australia at Test, One Day International and Twenty20 International levels.  Nicknamed SOS ("Son of Swampy"), he is a left-handed opening batsman and very occasional spin bowler. Chamani Roshini Seneviratne (born 14 November 1978 in Anuradhapura) is a Sri Lankan cricketer.  She scored Sri Lanka's only century in Women's Test cricket, with an unbeaten 105 against Pakistan in April 1998.  She also did it on her debut.  By scoring a test century on debut,she became only the eight batswoman to score a test hundred on debut.  After Chamani Seneviratne's century on debut, in Sri Lanka cricket's history the first-ever test centurions on debuts for both Sri Lanka men's national cricket team as well as Sri Lanka women's national cricket team came on debuts of Brendon Kuruppu and Seneviratne, respectively.  An all-rounder, she has played one Test and 47 One Day Internationals for Sri Lanka.  Chamani Seneviratne has scored the most number of runs on debut test for Sri Lanka (148 runs in both innings) and she is also the leading runscorer for Sri Lanka in test matches, despite Sri Lanka Women's managing to play their only test in 1998.  Her 148 runs on debut was also the fifth-highest by a woman on test debut. The Australia national cricket team, represents the country of Australia in international cricket.  It is the joint oldest team in Test cricket history, having played in the first ever Test match in 1877.  The team also plays One Day International cricket and Twenty20 International, participating in both the first ODI, against England in the 1970–71 season and the first Twenty20 International, against New Zealand in the 2004–05 season, winning both games.  The team draws its players from teams playing in the Australian domestic competitions – the Sheffield Shield, the Australian domestic limited-overs cricket tournament and the Big Bash League. The Australian cricket team toured Sri Lanka from 18 July to 9 September 2016 to play three Test matches, five One Day Internationals (ODIs), two Twenty20 Internationals (T20Is) matches and a first-class practice match.  The Test series was played for Warne-Muralitharan Trophy, with Sri Lanka winning 3–0, their first ever series whitewash against Australia.  As a result, Australia slipped from first to third in the ICC Test Championship; Sri Lanka, who had started the series ranked seventh, moved up to sixth. The Western Australia cricket team, nicknamed the Western Warriors, represent the Australian state of Western Australia in Australian domestic cricket.  The team is selected and supported by the Western Australian Cricket Association (WACA), and plays its home games at the WACA Ground in Perth.  The team mainly plays matches against other Australian states in the first-class Sheffield Shield competition and the limited-overs Matador BBQs One-Day Cup, but occasionally plays matches against touring international sides.  Western Australia previously also fielded sides at Twenty20 level, but was replaced by the Perth Scorchers for the inaugural 2011–12 season of the Big Bash League.  Western Australia's current captain is Mitchell Marsh, and the current coach is Justin Langer. The Indian cricket team toured Sri Lanka from 6 August to 1 September 2015 to play a tour match and three Test matches.  On 27 June, Sri Lankan batsman Kumar Sangakkara said he would retire from international cricket after the second Test of the series.  The Board of Control for Cricket in India (BCCI) and Sri Lanka Cricket Board confirmed the schedule of India's tour to Sri Lanka in August to September 2015.  The tour started with a three-day warm-up game against Sri Lanka Board President's XI, followed by three Test matches.  The Test matches were played at Galle, P Sara Oval, and SSC Colombo.  The Indian team arrived in Sri Lanka on 4 August 2015. The South African cricket team toured Sri Lanka from 20 July to 6 August 2013.  The tour consisted of five One Day International and three Twenty20 International matches.  Sri Lankan ODI captain Angelo Mathews was suspended for the first two ODI matches due to maintaining a slow over-rate during the final match of the West Indies tri-nation series.  The other members of the Sri Lanka team were fined 40% of their match fees.  Dinesh Chandimal served as captain in Mathews' stead making him, at 23, the youngest ODI captain in the history of Sri Lankan cricket.
