Smith made his club debut for Parramatta in round 9 of the 2017 season, playing at five-eighth against the North Queensland Cowboys and scoring a try. On 5 July 2017, Smith resigned with the club on a one-year extension due to good form. With Clint Gutherson and Bevan French injured, Smith moved to fullback and the end of the season, and finished the year of strongly playing 15 games (including two finals) and scoring six tries. In the elimination final match against the North Queensland Cowboys, Smith went from hero to villain in the space of 80 minutes. In the first half, Smith scored a length of the field try to make the score 10-6 at half time to Parramatta. In the second half, North Queensland playmaker Michael Morgan put up a routine bomb, in the resulting play Smith allowed the ball to bounce and did not attempt to catch it. Smith grabbed the ball on the second bounce but North Queensland player John Asiata raced up behind and stole the ball off Smith to score. This changed the momentum of the match and North Queensland went on to win 24-16.
