Playing career
Sian Williams was born in Wrexham, Clwyd on 4 April 1993. , her official Wales Rugby Union biography states that she is 1.62 m tall, and weighs 74 kg. Williams has been playing rugby since she was eight, when she played with her brothers. She was called up for the Wales women's under-20 national rugby union team, and captained the team in a victory over England in 2011. She made her debut for the Wales women's national rugby union team that same year, playing against Scotland in the 2011 Women's Six Nations Championship.

Outside of rugby, she was a logistics mover with the rank of Senior Aircraftwoman for the Royal Air Force. She had joined the RAF in 2008, and played for the RAF Rugby Union Women's team and the Combined Services' Women teams. That was until 10 February 2016, when it was announced that Williams had signed a professional rugby contract, having been granted elite athlete status by the RAF meaning that she would continue to be employed by the forces while being able to train full-time.

It was the first time any Welsh woman had signed a professional rugby contract. She previously lived in Oxford and would commute three times a week to train with the national team, and twice a week to Worcester to train with her club. Following the signing of the professional contract, Williams was re-located to RAF St Athan, where she could train with Wales head coach Rhys Edwards on a full-time basis for the next two years.
