Sia Kate Isobelle Furler (born 18 December 1975), better known as Sia, is an Australian downtempo, pop, and jazz singer and songwriter. She is vegetarian and participated in an advertisement with her dog Pantera, for PETA Asia-Pacific to encourage pet neutering.

In June 2010, Furler’s official website announced that all scheduled promotional events and shows had been cancelled due to her poor health. She cited extreme lethargy and panic attacks and considered retiring permanently from performing and touring.

Four months later, in an ARIA Awards interview Furler said her health was improving after rest and thyroid hormone replacement therapy. Furler has said she will release an album in the summer of 2012 and will refrain from touring temporarily.
