In 2014, Peel became directly aligned with the Fremantle Dockers of the Australian Football League, an arrangement which saw Fremantle's reserve players playing exclusively for Peel in the WAFL for the first time. In 2015, the second season of this arrangement, Peel qualified for the finals for the first time in its history, finishing third on the ladder with a club-best record of 13–7. Due to Fremantle's decision to rest a host of its key AFL players ahead of their finals campaign, the majority of Peel's usual Fremantle contingent was called up for AFL duties, which impacted Peel's ability to field a competitive team against West Perth in the qualifying final. As a result, Peel was blown out of the water by West Perth, losing their first finals game 145–36. Despite regaining many of their Fremantle players for their semi-final clash against East Perth the following week, they were knocked out of the finals with an 84–62 defeat at the hands of the Royals.
