Court gave birth to her first child in 1972, but returned to tennis later in the year and won three major singles titles in 1973.

Court is also one of only six tennis players to win a double career Grand Slam in two disciplines, matching Roy Emerson, Martina Navratilova, Frank Sedgman, Doris Hart, and Serena Williams.

The family lived in a "very modest, two bedroom, thin-walled, asbestos dwelling with a tin roof" and did not own a car during her early childhood.

[4] She played a variety of sports as a child, including basketball, cricket, softball and soccer, and had a reputation as a tomboy, joining "a group of neighbourhood boys who took pleasure in climbing trees, swinging on ropes over the river, and hitching free rides on trucks as they slowed".

[5] Court received her early education at St Bridget's, the local Catholic parochial school.

She later credited Rutter with encouraging her to pursue tennis professionally and developing her "killer instinct" and sense of sportsmanship.

[9][10] The next year, she lost the Wimbledon singles final to Evonne Goolagong while pregnant[11] with her first child, Daniel, who was born in March 1972.

Four months later, Billie Jean King beat Riggs in the Battle of the Sexes match in the Houston Astrodome.

[16] Since 2012, the arena has attracted calls for its name to be changed on the basis of Court's statements against gay and lesbian rights.

Court was dubbed "The Aussie Amazon" because she did weights, circuit training and running along sandy hillsides.

[24] The mixed doubles finals of those years were not played because of bad weather and the titles are shared by both of the finalist pairs.

In 1983, she gained a theological qualification from the Rhema Bible Training Centre, and in 1991 was ordained as an independent Pentecostal minister and so speaks publicly about her faith.

[38] Since 2010, she has been the president of Victory Life International, a network of like-minded churches, and is a long-standing patron of the Australian Family Association and Drug Free Australia.

The letter, and further follow-up interviews, again led to calls from some Australians and tennis players to rename the Margaret Court Arena.

[18][46] Some politicians, including Prime Minister Malcolm Turnbull, rejected calls for the change of name, saying the name celebrates Margaret Court as a tennis player.

[47] In June 2017, Russell Jackson wrote that Court had always held bigoted views, which he described as "stubbornly immovable", citing her support for apartheid in 1970 ("South Africans have this thing better organised than any other country, particularly America") and her criticisms of Navratilova in 1990 ("a great player but I'd like someone at the top who the younger players can look up to.

[48] On 23 January 2019, Anna Wintour, in her keynote address for the Australian Open's Inspirational Series, renewed calls for the arena's renaming.

[49] Court responded by saying she was "disappointed" that someone "coming from America" was "unable to tolerate views that were not in line with her own" and "[is] telling us in this nation what to do".

[50] Later in the year, Court called on Tennis Australia to honour her and the 50th anniversary of her 1970 Grand Slam in the same way as it honoured Rod Laver earlier in 2019, arguing that the organisation should disregard her views on same-sex marriage, as her tennis achievements are from "a different phase of my life from where I am now and if we are not big enough as a nation and a game to face those challenges there is something wrong."

[51] During the tournament, however, high-profile guests Martina Navratilova and John McEnroe paraded a banner calling for the Margaret Court Arena to be renamed in honour of four-time Australian Open champion Evonne Goolagong.

[52][53] In 2020, her Margaret Court Community Outreach charity was denied a Lotterywest grant for a freezer truck on the basis of her public statements on gay people.

[55] Note: The shared mixed doubles titles at the Australian Championships/Open in 1965 and 1969 are not always counted in Court's Grand Slam win total because the finals were never played.
