Orla made her Rhinos debut while still part of the club's Academy in 2019 and was then elevated to the first team squad, although she had to wait over a year to play again after the Women's competition was cancelled due to Covid.  She started the first game of the 2021 season against York and then earned a regular spot in Forsell's squad, including starting in the Challenge Cup semi final against St Helens. By the end of the season, she had only missed one game, plus she also scored three tries at bothloose forward and hooker. She also appeared in her first final as Leeds were defeated by St Helens in the Grand Final.
