Netball is a ball sport played by two teams of seven players. Netball is most popular in many Commonwealth nations, specifically in schools, and is predominantly played by women. According to the INF, netball is played by more than 20 million people in more than 80 countries.^[13][14] Major domestic leagues in the sport include the Netball Superleague in Great Britain, Suncorp Super Netball in Australia and the ANZ Premiership in New Zealand. Four major competitions take place internationally: the quadrennial World Netball Championships, the Commonwealth Games, and the yearly Quad Series and Fast5 Series. In 1995, netball became an International Olympic Committee recognised sport, but it has not been played at the Olympics.

Games are played on a rectangular court with raised goal rings at each end. Each team attempts to score goals by passing a ball down the court and shooting it through its goal ring. Players are assigned specific positions, which define their roles within the team and restrict their movement to certain areas of the court. During general play, a player with the ball can hold on to it for only three seconds before shooting for a goal or passing to another player. The winning team is the one that scores the most goals. Netball games are 60 minutes long. Variations have been developed to increase the game's pace and appeal to a wider audience.

Its development, derived from early versions of basketball, began in England in the 1890s. By 1960, international playing rules had been standardised for the game, and the International Federation of Netball and Women's Basketball (later renamed the International Netball Federation (INF)) was formed. As of 2019, the INF comprises more than 70 national teams organized into five global regions.

Netball emerged from early versions of basketball and evolved into its own sport as the number of women participating in sports increased. Basketball was invented in 1891 by James Naismith in the United States. The game was initially played indoors between two teams of nine players, using an association football that was thrown into closed-end peach baskets.^[15] Naismith's game spread quickly across the United States and variations of the rules soon emerged. Physical education instructor Senda Berenson developed modified rules for women in 1892; these eventually gave rise to women's basketball. Around this time separate intercollegiate rules were developed for men and women.^[16] The various basketball rules converged into a universal set in the United States.

Martina Bergman-Österberg introduced a version of basketball in 1893 to her female students at the Physical Training College in Hampstead, London.^[17] The rules of the game were modified at the college over several years: the game moved outdoors and was played on grass; the baskets were replaced by rings that had nets; and in 1897 and 1899, rules from women's basketball in the United States were incorporated.^[16][18] Österberg's new sport acquired the name "net ball".^[19] The first codified rules of netball were published in 1901 by the Ling Association, later the Physical Education Association of the United Kingdom.^[12][20] From England, netball spread to other countries in the British Empire. Variations of the rules and even names for the sport arose in different areas: "women's (outdoor) basketball" arrived in Australia around 1900 and in New Zealand from 1906,^[12][21] while "netball" was being played in Jamaican schools by 1909.^[22]

From the start, it was considered socially appropriate for women to play netball; netball's restricted movement appealed to contemporary notions of women's participation in sports, and the sport was distinct from potential rival male sports.^[12][23] Netball became a popular women's sport in countries where it was introduced and spread rapidly through school systems. School leagues and domestic competitions emerged during the first half of the 20th century,^[24][25] and in 1924 the first national governing body was established in New Zealand.^[21] International competition was initially hampered by a lack of funds and varying rules in different countries. Australia hosted New Zealand in the first international game of netball in Melbourne on 20 August 1938; Australia won 40–11.^[21] Efforts began in 1957 to standardise netball rules globally: by 1960 international playing rules had been standardised, and the International Federation of Netball and Women's Basketball, later the International Netball Federation (INF), was formed to administer the sport worldwide.^[13]

Representatives from England, Australia, New Zealand, South Africa, and the West Indies were part of a 1960 meeting in Sri Lanka that standardised the rules for the game.^[26] The game spread to other African countries in the 1970s.^[27][28] South Africa was prohibited from competing internationally from 1969 to 1994 due to apartheid.^[29][30] In the United States, Netball's popularity also increased during the 1970s, particularly in the New York area, and the United States of America Netball Association was created in 1992.^[31] The game also became popular in the Pacific Island nations of the Cook Islands, Fiji and Samoa during the 1970s.^[32] Netball Singapore was created in 1962,^[33] and the Malaysian Netball Association was created in 1978.^[34]

In Australia, the term women's basketball was used to refer to both netball and basketball.^[35] During the 1950s and 1960s, a movement arose to change the Australian name of the game from women's basketball to netball in order to avoid confusion between the two sports. The Australian Basketball Union offered to pay the costs involved to alter the name, but the netball organisation rejected the change.^[35] In 1970, the Council of the All Australia Netball Association officially changed the name to "netball" in Australia.^[12]

In 1963, the first international tournament was held in Eastbourne, England. Originally called the World Tournament, it later became known as the World Netball Championships.^[36] Following the first tournament, one of the organisers, Miss R. Harris, declared,

The World Netball Championships have been held every four years since then. The World Youth Netball Championships started in Canberra in 1988, and have been held roughly every four years since. In 1995, the International Olympic Committee recognized the International Federation of Netball Associations.^[12] Three years later netball debuted at the 1998 Commonwealth Games in Kuala Lumpur.^[13] Other international competitions also emerged in the late 20th century, including the Nations Cup and the Asian Netball Championship.^[37][38]

As of 2006, the IFNA recognises only women's netball.^[39] Men's netball teams exist in some areas but attract less attention from sponsors and spectators.^[40] Men's netball started to become popular in Australia during the 1980s, and the first men's championship was held in 1985.^[39] In 2004, New Zealand and Fiji sent teams to compete in the Australian Mixed and Men's National Championships.^[39] By 2006, mixed netball teams in Australia had as many male participants as rugby union.^[41][42] Other countries with men's national teams include Canada, Fiji, Jamaica, Kenya, Pakistan and the United Arab Emirates.^[43] Unlike women's netball at elite and national levels, men's and mixed gender teams are largely self-funded.^[39]

An all-transgender netball team from Indonesia competed at the 1994 Gay Games in New York City.^[44] The team had been the Indonesian national champions.^[44] At the 2000 Gay Games VI in Sydney, netball and volleyball were the two sports with the highest rates of transgender athletes participating.^[45] There were eight teams of indigenous players, with seven identifying as transgender.^[45] They came from places like Palm Island in northern Queensland, Samoa, Tonga and Papua New Guinea.^[45] Teams with transgender players were allowed to participate in several divisions including men's, mixed and transgender; they were not allowed to compete against the cisgender women's teams.^[45]

The objective of a game is to score more goals than the opposition. Goals are scored when a team member positioned in the attacking shooting circle shoots the ball through the goal ring. The goal rings are 380 millimetres (15 in) in diameter and sit atop 3.05-metre (10.0 ft)-high goal posts that have no backboards.^[46] A 4.9-metre (16 ft)-radius semi-circular "shooting circle" is an area at each end of the court. The goal posts are located within the shooting circle. Each team defends one shooting circle and attacks the other.^[46] The netball court is 30.5 metres (100 ft) long, 15.25 metres (50.0 ft) wide, and divided lengthwise into thirds. The ball is usually made of leather or rubber, measures 680 to 710 millimetres (27 to 28 in) in circumference, and weighs 397 to 454 grams (14.0 to 16.0 oz).^[47][48] A normal game consists of four 15-minute quarters^[47][49] and can be played outdoors or in a covered stadium.

Each team is allowed seven players on the court.^[50] Each player is assigned a specific position, which limits their movement to a certain area of the court. A "bib" worn by each player contains a one- or two-letter abbreviation indicating this position.^[51] Only two positions are permitted in the attacking shooting circle, and can therefore shoot for a goal. Similarly, only two positions are permitted in the defensive shooting circle; they try to prevent the opposition from shooting goals. Other players are restricted to two thirds of the court, with the exception of the Centre, who may move anywhere on the court except for a shooting circle.^[52]

At the beginning of every quarter and after a goal has been scored, play starts with a player in the centre position passing the ball from the centre of the court. These "centre passes" alternate between the teams, regardless of which team scored the last goal. When the umpire blows the whistle to restart play, four players from each team can move into the centre third to receive the pass. The centre pass must be caught or touched in the centre third.^[53][54] The ball is then moved up and down the court through passing and must be touched by a player in each adjacent third of the court. Players can hold the ball for only three seconds at any time. It must be released before the foot they were standing on when they caught it touches the ground again.^[47] Contact between players is only permitted if it does not impede an opponent or the general play. When defending a pass or shot players must be at least 90 centimetres (35 in) away from the player with the ball. If illegal contact is made, the player who contacted cannot participate in play until the player taking the penalty has passed or shot the ball.^[55] If the ball is held in two hands and either dropped or a shot at goal is missed, the same player cannot be the first to touch it unless it first rebounds off the goal.^[56]

Indoor netball is a variation of netball, played exclusively indoors, in which the playing court is often surrounded on each side and overhead by a net. The net prevents the ball from leaving the court, permitting faster play by reducing playing stoppages.^[57]

Different forms of indoor netball exist. In a seven-per-side version called "action netball", seven players per team play with rules similar to netball. However, a game is split into 15-minute halves with a three-minute break in between. This version is played in Australia,^[58] New Zealand,^[59] South Africa^[60] and England.^[61]

A six-per-side version of the sport is also played in New Zealand. Two Centres per team can play in the whole court except the shooting circles; the remaining attacking and defending players are each restricted to one half of the court, including the shooting circles. The attacking and Centre players may shoot from outside the shooting circle for a two-point goal.^[62][63]

A five-per-side game is also common in indoor netball. Players can move throughout the court, with the exception of the shooting circles, which are restricted to certain attacking or defending players.

Fast5 (originally called Fastnet) is a variation on the rules of netball designed to make games faster and more television-friendly. The World Netball Series promotes it to raise the sport's profile and attract more spectators and greater sponsorship.^[64][65] The game is much shorter, with each quarter lasting only six minutes and only a two-minute break between quarters.^[66] The coaches can give instructions from the sideline during play, and unlimited substitutions are allowed.^[66] Like six-per-side indoor netball, attacking players may shoot two-point goals from outside the shooting circle.^[66][67] Each team can separately nominate one "power play" quarter, in which each goal scored by that team is worth double points and the centre pass is taken by the team that conceded the goal.^[66]

Netball has been adapted in several ways to meet children's needs. The rules for children are similar to those for adults, but various aspects of the game (such as the length of each quarter, goal height, and ball size) are modified.

Fun Net is a version of netball developed by Netball Australia for five- to seven-year-olds. It aims to improve basic netball skills using games and activities.^[68] The Fun Net program runs for 8–16 weeks. There are no winners or losers. The goal posts are 2.4 metres (7 ft 10 in) high, and a smaller ball is used.^[69]

Netball Australia also runs a modified game called Netta aimed at 8- to 11-year-olds.^[70] The goal height and ball size are the same as for adults, but players rotate positions during the game, permitting each player to play each position.^[71] Netta was created to develop passing and catching skills. Its rules permit six seconds between catching and passing the ball, instead of the three seconds permitted in the adult game.^[70] Most players under 11 play this version at netball clubs.^[71]

A version called High Five Netball is promoted by the All England Netball Association.^[72] It is aimed at 9- to 11-year-old girls and includes only five positions.^[72] The players swap positions during the game.^[73] When a player is not on the court, she is expected to help the game in some other way, such as being the timekeeper or scorekeeper.^[72] High Five Netball has four six-minute quarters.^[72][73]

The recognised international governing body of netball is the International Federation of Netball Associations (IFNA), based in Manchester, England.^[20] Founded in 1960, the organisation was initially called the International Federation of Netball and Women's Basketball.^[13] The IFNA is responsible for compiling world rankings for national teams, maintaining the rules for netball and organising several major international competitions.

As of July 2019, the IFNA has 53 full and 19 associate national members in five regions.^[74] Each region has an IFNA regional federation.^[75]

The IFNA is affiliated with the General Association of International Sports Federations, the International World Games Association and the Association of IOC Recognised International Sports Federations.^[13] It is also a signatory to the World Anti-Doping Code.^[76]

Netball is a popular participant sport in countries of the Commonwealth of Nations.^[77][78] Non-Commonwealth entities with full IFNA membership include Switzerland, Taiwan, Thailand, Argentina, Bermuda, the Cayman Islands and the United States, along with former Commonwealth members Zimbabwe, Ireland and Hong Kong.^[79] According to the IFNA, over 20 million people play netball in more than 80 countries.^[13][14] International tournaments are held among countries in each of the five IFNA regions, either annually or every four years. School leagues and national club competitions have been organised in England,^[80] Australia,^[12] New Zealand^[21] and Jamaica^[22] since the early twentieth century. Franchise-based netball leagues did not emerge until the late 1990s. These competitions sought to increase the profile of the sport in their respective countries. Despite widespread local interest, participation was largely amateur.^[81]

Netball was first included in the 1998 Commonwealth Games and has been a fixture ever since; it is currently one of the "core" sports that must be contested at each edition of the Games.^[82]

The major international tournament in Africa is organised by the Confederation of African Netball Associations, which invites teams from Botswana, Namibia, Zambia, Malawi, South Africa, Lesotho, Swaziland, Zimbabwe and the Seychelles to take part.^[83] The tournament is hosted by a country within the region; senior and under 21 teams compete.^[83] The tournament has served as a qualifier for the World Championships.^[84] South Africa launched a new domestic competition in 2011 called Netball Grand Series. It features eight regional teams from South Africa and is aimed at increasing the amount of playing time for players. It runs for 17 weeks and replaces the National Netball League, which was played over only two weeks. According to Proteas captain Elsje Jordaan, it was hoped that the competition would create an opportunity for players to become professional.^[85]

The American Federation of Netball Associations (AFNA) hosts two tournaments each year: the Caribbean Netball Association (CNA) Under 16 Championship and the AFNA Senior Championship.^[86] The CNA championship involves two divisions of teams from the Caribbean islands. In 2010 five teams competed in two rounds of round robin matches in the Championship Division, while four teams competed in the Developmental Division.^[87] Jamaica, which has lost only once in the tournament,^[88] decided not to play the 2011 tournament.^[87] The AFNA Senior Championship includes Canada and the US along with the Caribbean nations. The tournament serves as a qualifier for the World Championship. Jamaica, with its high ranking, does not have to qualify; this leaves two spots to the other teams in the tournament.^[89]

The Asian Netball Championship is held every four years. The seventh Asian games were held in 2009 and featured Singapore, Thailand, Maldives, Taiwan, Malaysia, Sri Lanka, Hong Kong, India and Pakistan.^[90] There is also an Asian Youth Netball Championship for girls under 21 years of age, the seventh of which was held in 2010.^[91]

The major netball competition in Europe is the Netball Superleague, which features nine teams from England, Wales and Scotland.^[92][93] The league was created in 2005.^[19] Matches are broadcast on Sky Sports.^[94]

Netball has been featured at the Pacific Games, a multi-sport event with participation from 22 countries from around the South Pacific.^[95] The event is held every four years and has 12 required sports; the host country chooses the other four. Netball is not a required sport and has missed selection, particularly when former French or American territories host the games.^[96]

The ANZ Championship was a Trans-Tasman competition held between 2008 and 2016 that was broadcast on television in both New Zealand and Australia. It was contested among ten teams from Australia and New Zealand. It began in April 2008, succeeding Australia's Commonwealth Bank Trophy and New Zealand's National Bank Cup as the pre-eminent netball league in those countries.^[97] The competition was held annually between April and July, consisting of 69 matches played over 17 weeks. The ANZ Championship saw netball become a semi-professional sport in both countries, with increased media coverage and player salaries.^[98][99] The competition was replaced by new leagues in 2017, the Suncorp Super Netball (Australia) and ANZ Premiership (New Zealand).

There are four major international netball competitions; the Netball World Cup, Netball at the Commonwealth Games, Netball Quad Series and Fast5 Netball World Series.

Netball's important competition is the World Netball Championships (also known as the Netball World Cup), held every four years. It was first held in 1963 at the Chelsea College of Physical Education at Eastbourne, England, with eleven nations competing. Since its inception the competition has been dominated primarily by the Australian and New Zealand teams, which hold ten and four titles, respectively. Trinidad and Tobago is the only other team to win a championship title. That title, won in 1979, was shared with New Zealand and Australia; all three teams finished with equal points at the end of the round robin, and there were no finals.^[100]

The Fast5 Series is a competition among the top six national netball teams, as ranked by the INF World Rankings.^[101] It is organised by the INF in conjunction with the national governing bodies of the six competing nations, UK Sport, and the host city's local council.^[102] The All England Netball Association covers air travel, accommodation, food and local travel expenses for all teams, while the respective netball governing bodies cover player allowances.^[103] It is held over three days, with each team playing each other once during the first two days in a round-robin format. The four highest-scoring teams advance to the semi-finals; the winners face each other in the Grand Final.^[104] The competition features modified fastnet rules and has been likened to Twenty20 cricket and rugby sevens.^[105][106] A new format featuring shorter matches with modified rules was designed to make the game more appealing to spectators and television audiences.^[105] The World Netball Series was held annually in England from 2009 to 2011.

Netball gained Olympic recognition in 1995 after 20 years of lobbying.^[12][107] Although it has never been played at the Summer Olympics, politicians and administrators have been campaigning to have it included in the near future.^[108][109] Its absence from the Olympics has been seen by the netball community as a hindrance in the global growth of the game by limiting access to media attention and funding sources.^{[27][110][111]} Some funding sources became available with recognition in 1995,^[112] including the International Olympic Committee, national Olympic committees, national sport organisations, and state and federal governments.^[112][113]

One study found that over 14 weeks of play about 5% of people develop an injury.^[114] The most common injury is of the ankle (usually lateral ligament ankle strain and less often an ankle fracture).^[114][115] Knee injuries were less common and included anterior cruciate ligament injuries.^[114] The main cause of these injuries is believed to be due to incorrect landing.^[114] One study found not warming-up as a risk factor.^[115] Hypermobility (having a range of motion beyond normal limits) has been associated with injuries in one small study.^[116] Higher grade players, in both senior and junior competitions, are more susceptible to injuries than lower grade players, due to the high intensity and rapid pace of the game.^[114]

In October 2005, Australian captain Liz Ellis, tore her ACL in a match against New Zealand. This injury ruled her out of the chance to play at the 2006 Melbourne Commonwealth games.^[117] In October 2014, Casey Kopua ruptured the patella tendon in her left knee resulted in her missing up to 6 months of netball.^[118]
