The 2017–18 Ashes series is a forthcoming series of Test cricket matches to be contested between England and Australia for The Ashes.
 The series will be played at five venues across Australia between 23 November 2017 and 8 January 2018.
Helen Elizabeth "Betty" Archdale (21 August 1907 – 11 January 2000) was an educationalist and cricketer.
 She was a captain of the English women's cricket team in 1934 and 1935.
 In 1934/35 she led the first English cricket team to tour Australia and New Zealand, the result of which was a 2-0 victory over Australia.
 This tour did much both to raise the status of women's cricket and to heal some of the damage done to Anglo-Australian cricket relations by bodyline two years earlier.
Centenary Test refers to two matches of Test cricket played between the English cricket team and the Australian cricket team, the first in 1977 and the second in 1980.
 These matches were played to mark the 100th anniversaries of the first Test cricket matches played in Australia (1877) and in England (1880) respectively.
 Neither match was played for The Ashes.
Robert "Bob" Elliott Storey Wyatt (2 May 1901, Milford Heath House, Surrey, England – 20 April 1995, Treliske, Truro, Cornwall) was an English cricket player.
 He played for Warwickshire, Worcestershire, and the English cricket team.
Before the beginning of the 2005 English cricket season began, a resurgent English cricket team had won four Test series in a row, going unbeaten through the 2004 calendar year.
 The start of the international season saw England defeat Bangladesh 2–0 in their two-match series, winning both Tests by an innings.
 This was followed by a tri-nations one-day tournament that also featured Australia.
 However, all eyes were on the Ashes.
 Australia still started as favourites, but England, for the first time in years, were expected to put up a real challenge to Aussie supremacy.
The English cricket team toured India during February, March and April 2006.
 The English cricket team was aspiring to maintain the form that took them to second place in the ICC Test Championship before their disastrous spell against Pakistan, and which helped win the 2005 Ashes series at home to Australia.
 This goal was substantially hindered by the usual stomach complaints which nearly always dog the English team in the opening weeks of Indian tours, and a recurrence of an injury to the captain Michael Vaughan; the swing bowler Simon Jones and the absence of Ashley Giles who missed the tour for an operation.
 As well as this, stand-in captain Marcus Trescothick flew home for "personal reasons", not wishing to divulge further, leaving Andrew Flintoff, who missed the birth of his son, to take on the title of skipper for the first time having to captain two maiden international cricketers on the English side: Alastair Cook and Monty Panesar as well as Shanthakumaran Sreesanth, Piyush Chawla and Munaf Patel for the home team.
International cricket played in the 2006 cricket season is defined as matches scheduled between May and August 2006 in all cricketing countries, as well as all international matches scheduled for the 2006 English cricket season.
 Matches between January and April are defined as belonging to the 2005–06 season, while matches between September and December are defined as the 2006–07 season.
 The main matches in this period were played in England, as this was in the middle of the English cricket season, but the third edition of the ICC Intercontinental Cup is defined as a part of the 2006 season, even though the tournament will stretch into February 2007, and three A teams are also scheduled to tour the northwestern part of Australia in June and July 2006.
The Barmy Army is a semi-organised group of English cricket fans which arranges touring parties for some of its members to follow the English cricket team on overseas tours.
 The name is also applied to followers of the team who join in with match day activities in the crowd, but do not necessarily travel as part of an organised tour.
The 2004 English cricket season saw the English cricket team record a 4-0 Test series whitewash over the West Indies and a comfortable 3-0 win over New Zealand.
 Their one-day form was sporadic, however.
 In the Natwest Trophy, they failed to make the final, which saw New Zealand defeat the West Indies by 107 runs.
 In the Natwest Challenge, they beat India 2-1.
 In domestic cricket, Warwickshire won the County Championship.
The England cricket team is scheduled to tour Australia between November 2017 and February 2018 to play five Tests and five One Day Internationals (ODIs).
 They will also take part in a three nation Twenty20 International (T20I) tournament, along with New Zealand, who will co-host the tournament along with Australia.
 The Test series will form part of the 2017–18 Ashes series.
 In May 2017, it was confirmed that the WACA Ground would host the Test and ODI in Perth, as the planned new ground was unable to open in time.
