Specialising in the javelin throw, Situ is a two-time gold medalist at both the Paralympics and the IPC Athletics World Championships and is the first female South African black athlete to win a Paralympic gold medal.
Situ was born in Kokstad, South Africa in 1971. At the age of twelve she experienced weakness in her legs which resulted in an inability to walk. Medical tests discovered a tuberculosis infection in her spine which resulted in Situ entering a two-year semi-coma, and was left with paralysis from the fourth vertebra down, leaving her wheelchair bound.
Situ first came to the international stage in 1998 when she represented South Africa at her first IPC Athletics World Championships, held in Birmingham, England. There she entered both the javelin and discus events, winning gold in the javelin with a best throw of 14.45 metres, and bronze in the discus throw.
This led her to the 2000 Summer Paralympics in Sydney where she won a gold in the F52-54 javelin and a silver in the F51-54 discus. By taking gold in Sydney she became the first South African female black athlete to win a Paralympic title.
2003 saw Situ recognized for her achievements by her country when she was awarded the Order of Ikhamanga (silver) for her contributions to sport.
In Athens, Situ successfully defended her javelin title at the 2004 Summer Paralympics. Although not finishing on the podium in either the shot put or the discus, she was recognized by the International Paralympic Committee as the female athlete who best embodied the spirit of the Games when she was awarded the Whang Youn Dai Achievement Award.
After Athens, Situ entered a barren period competitively, failing to reach the podium at the 2008 Summer Paralympics in Beijing. She recovered some form in 2011, when she won bronze at Christchurch World Championships, but the emergence of world class competitors, such as Tunisia's Hania Aidi and China's Yang Liwan, made title challenges a difficult task. At the 2012 Summer Paralympics in London Situ threw a distance of 16.22 metres, but she fell short of the podium in fourth place.
In between the 2012 and 2016 Summer Paralympics, Situ claimed two more world bronze medals, at Lyon (2013) and Doha (2015), both in the javelin. At Rio, in the 2016 Paralympics, Situ achieved a personal best in the javelin, throwing a 17.90 metre mark in her third round to take her first Paralympic medal in twelve years, a bronze. At the Rio Games she was also recognized by her country, being given the honour of flag bearer during the opening ceremony.
