Sia's Real Name: Sia Kate Isobelle Furler

Quick answer: Sia's documented original name is Sia Kate Isobelle Furler. Biography.com uses that form and dates her birth to December 18, 1975, in Adelaide, Australia. The Guardian independently identifies her as Sia Furler, an Adelaide-born singer who later worked in England (Biography; The Guardian).

Real name and early life

She is known professionally as Sia. Biography.com says she was born Sia Kate Isobelle Furler on December 18, 1975, in Adelaide, to a mother involved in the arts and a musician father, and that she moved to England in her early twenties to pursue music. The Guardian's 2016 interview likewise says she came to England from Adelaide in the late 1990s and became a vocalist with Zero 7. Biography.com also records the Zero 7 period, including appearances on the group's albums When It Falls (2004) and The Garden (2006), and her first solo album, Healing Is Difficult, followed by Colour the Small One, Some People Have Real Problems, and later We Are Born. Those early solo records, Biography.com says, put her career on a new track before the later pop breakthrough; the same profile notes that she had remained a Zero 7 member even as that solo recording work later expanded.

Career highlights

Both sources treat her later solo fame and her work as a songwriter for other pop stars as the core of the career. Biography.com highlights the hits "Chandelier" and "Cheap Thrills," the album 1000 Forms of Fear, and later releases This Is Acting and Everyday Is Christmas. It also records that she wrote Rihanna's No. 1 hit "Diamonds," appeared with David Guetta on the Top 10 single "Titanium," and that most tracks on This Is Acting had originally been offered to other singers. The Guardian, interviewing her around This Is Acting, describes her as a chart-topping solo artist who also became a go-to songwriter for major pop acts and who has often avoided a conventional celebrity image, including appearing with her face partly obscured. Biography.com notes that when she re-emerged in that era she often wore a wig that covered her face.
