2015 In 2015, Scott captained the
Cronulla-Sutherland Sharks'
S. G. Ball Cup team to the premiership. In July 2015, he was named the Player of the Tournament, playing for
New South Wales at the Australian Schoolboys carnival in
Wollongong. In September 2015, he signed a three-year contract with the
Melbourne Storm starting in 2016, beating 11 rival NRL clubs to his signature. In round 2 of the
2016 NRL season, he made his
NRL debut for the Melbourne club against the
Gold Coast Titans. Scott had his Melbourne Storm jersey (cap 170) presented to him by Melbourne Storm coach
Craig Bellamy. In round 4 against the
Cronulla-Sutherland Sharks, he broke his leg, ruling him out for the rest of the season.
2017 In October, Scott was part of the Melbourne Storm's premiership winning team against the
North Queensland Cowboys in the
2017 NRL Grand Final.
2018 In round 11, Scott was sent off the field for punching
Manly Warringah Sea Eagles player
Dylan Walker, Scott being the first player in the last three years to be sent off. He played at centre for Melbourne in the
2018 NRL Grand Final which they lost 21-6 against the
Sydney Roosters at
ANZ Stadium.
2019 On 7 October, Scott earned his first representative jersey as he was named in the Australian side for the
2019 Rugby League World Cup 9s. Later that day, Scott was named at Centre for the U23 Australian squad. On 29 November, Scott signed a contract to join
Canberra until the end of the 2023 season. Scott was released by Melbourne despite having two years remaining on his contract.
2020 Scott made his debut for Canberra against the Gold Coast in round 1 of the
2020 NRL season which ended in a 24-6 victory. He missed large chunks of the 2020 season due to both indifferent form and injury, with his 2020 campaign ultimately ending when he hurt his right leg against Canterbury-Bankstown in round 16. After being cleared of a fracture, Scott ended up suffering an infection due to a plate in his leg from when he broke it back in 2016. The complications saw him miss the last four rounds of the competition and Canberra's finals campaign.
2021 On 23 August, Scott's playing contract with the Canberra club was terminated. The Canberra side released a statement saying "The board decided that Curtis Scott's prior behaviour and recent assault charge has brought the club into disrepute, and they could not ignore this and the responsibilities that his NRL playing contract entails. "The board said the club would continue to support Curtis Scott's ongoing rehabilitation and it will be in contact with NRL Welfare in this regard". The following day, it was also revealed that Scott had also been involved in a fist fight with teammate
John Bateman at a private function in 2020. Scott injured his hand during the incident but the matter was not reported to the police and was dealt with privately. ==Boxing career==
