Nick Kyrgios has built a reputation as one of tennis’s most recognizable and unpredictable personalities, but away from the court, family has remained an important part of his story. Born and raised in Canberra, Australia, Kyrgios comes from a multicultural household shaped by Greek and Malaysian heritage.
His family background has often attracted attention because of the different cultures, careers and personalities represented by the people closest to him. From his parents and two older siblings to his long-term partner Costeen Hatzi, the people around Kyrgios have played different roles during his rise in professional tennis.
Costeen Hatzi
Costeen Hatzi has been one of the most visible people in Kyrgios’ personal life in recent years. The interior designer and social media personality began dating the tennis player in late 2021.
Hatzi has frequently accompanied Kyrgios during tournaments and has appeared in photographs and social-media posts documenting their life together. Her presence has also made her familiar to tennis fans who follow Kyrgios beyond his matches.
The couple have generally shared selected moments from their relationship publicly while keeping many aspects of their private life away from the spotlight. Hatzi has also developed her own profile through interior design, lifestyle content and social media.
His Father
Kyrgios’ father, Giorgos Kyrgios, is of Greek heritage. He worked as a house painter after moving to Australia from Greece and helped raise Nick and his siblings in Canberra.
Unlike his famous son, Giorgos has largely stayed outside the international sporting spotlight. Nevertheless, his Greek background is an important part of Kyrgios’ identity.
Kyrgios has spoken over the years about his strong connection to his family and his Greek heritage. His father’s influence is part of a wider family story that combines European and Southeast Asian roots.
His Mother
Norlaila, commonly known as Nill Kyrgios, was born in Malaysia and has Malaysian royal ancestry. She was connected to the Selangor royal family before moving to Australia.
Nill later worked as a computer engineer and raised her children in Canberra. Her background gave Kyrgios a distinctive multicultural heritage, combining his father’s Greek roots with his mother’s Malaysian ancestry.
Her story has also been discussed in profiles of Kyrgios because she made the decision to build her life in Australia after leaving Malaysia. She has remained an important figure in her son’s life and has been seen supporting him during his tennis career.
Christos Kyrgios
Nick is the youngest of three siblings. His older brother, Christos Kyrgios, has worked in fitness and business and has been involved in some of Nick’s activities away from professional tennis.
Christos has occasionally appeared in media coverage surrounding his brother and has supported Nick through different stages of his career. His role has extended beyond that of a sibling, with his professional experience making him part of the wider team surrounding the tennis star.
The brothers have maintained a close connection despite Nick’s demanding international schedule.
Halimah Kyrgios
Nick’s older sister, Halimah Kyrgios, followed a very different professional path. She is a performer who has worked as a singer, dancer and musical-theatre actress.
Halimah has performed in major stage productions, including internationally recognized shows such as Aladdin and The King and I. Her career has taken her into the performing arts rather than professional sport.
Her achievements have given the Kyrgios family another connection to the entertainment world. While Nick became known through tennis, Halimah established her own identity on the stage.
Canberra Roots
Although Kyrgios has spent much of his adult life traveling internationally for tennis, Canberra remains central to his family story. He grew up there and developed his tennis career in Australia before becoming a global professional.
His upbringing was shaped by a household in which Greek and Malaysian traditions existed alongside Australian life. That multicultural background has remained part of the public identity Kyrgios has carried throughout his career.
Family members have also appeared in his player’s box at different points, providing a familiar support system during the pressures of professional competition.
A Private Circle
Despite his highly public tennis career, Kyrgios has generally kept some aspects of family life away from constant media attention. His parents and siblings occasionally attract coverage because of their connection to him, but they have largely pursued their own careers and interests.
That distinction is particularly noticeable with Halimah and Christos, whose professional lives are separate from Nick’s sporting achievements.
Kyrgios’ relationship with Hatzi has similarly received attention because she frequently appears alongside him, yet the couple have continued to decide how much of their personal life they want to share publicly.
Family Influence
Nick Kyrgios’ career has been defined by spectacular performances, injuries, controversies and an unusually outspoken personality. Behind that public image is a family with a considerably broader story.
His Greek-Australian father, Malaysian-born mother, older brother and performer sister each represent a different part of his background. Together, they help explain the multicultural environment in which Kyrgios grew up.
For fans interested in the person behind the tennis player, his family provides an important perspective. Kyrgios may have become internationally famous through sport, but his story began with a close-knit Canberra family whose Greek, Malaysian and Australian influences continue to form part of his identity.
