Sau made his Fiji Sevens debut in 2017 and an immediate impact on the World Rugby Sevens Series earned him the Rookie of the Season title and a place in the overall Series Dream Team.
The winger made his full international debut in XV-a-side in November 2018, scoring a hat-trick in Fiji's 68-7 victory over Uruguay.
Sau initially made his way in rugby league playing for local side, Saru Dragons. After a brief spell playing in the Cook Islands, the winger was encouraged to take up rugby sevens, and on that advice, joined Fijian club Red Rock.
In 2014 he was recruited as a Special Constable at Totogo Police Station in Suva and joined the Fiji Police rugby team.
Three years later, he was selected to represent Fiji Drua in the National Rugby Championship, and it was here where he caught the attention of Fiji Sevens Head Coach Gareth Baber. Since his international sevens debut in 2017, Sau has scored a total of 185 points (37 tries) in 58 matches.
He was named Impact Player at the 2018 Hong Kong Sevens, and won five gold medals and one bronze in the 2017/18 World Rugby Sevens Series.
He was part of the Fiji Sevens side that won silver at the Gold Coast 2018 Commonwealth Games and which finished overall runner-up in the 2017/18 World Rugby Sevens Series.
Sau joined the club from French club USA Perpignan, whom he joined in May 2018.
