On 14 February 2017 Papadopoulos joined Australian A-League club Brisbane Roar until the end of the season, as an injury replacement for Daniel Bowles, who was sidelined for at least 10 months with a serious knee injury. Despite representing Greece, the central defender has an Australian passport and is therefore not counted as a visa player. On 5 March 2017 he made his debut with the club in a 3–1 away win against Newcastle Jets. On 22 June 2017, the club has retained the ex-international defender's services for another 12 months after his midseason arrival early this year. Melbourne-born Papadopoulos played seven games at centre-back during the semi-finalists' 2016–17 season, providing cover for Luke De Vere and Jade North.
