Peel Thunder Football Club was formed in 1996 after the West Australian Football Commission (WAFC) granted a ninth licence in the WAFL to the Mandurah-Peel region. The licence was issued on the condition that the club be ready to compete in the 1997 Westar Rules seasonGeoff Miles was appointed as the club's inaugural coach and Phil Gilbert appointed captain. The Thunder managed just one win in 1997 and finished last on the ladder, with Scott Simister winning the inaugural best and fairest. They managed another one-win season in 1998, before going winless in 1999.

Between 1997 and 2014, the Thunder failed to qualify for the finals, with their best season coming in 2008 when they recorded an 8–12 win–loss record and a sixth-place finish. During that time, they collected nine wooden spoons, including three in a row twice (1997–99 & 2011–13), and finished second last seven times.

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.

In 2016, the Thunder finished the home and away season in fourth place on the ladder with an 11–9 record. Despite a drop off from 2015, Peel headed into the WAFL finals with a huge boost thanks to Fremantle's poor season in 2016. With Fremantle missing the finals in 2016, it provided Peel with a huge contingent of players for their finals campaign. Behind 17 Docker-listed players, the Thunder won three do-or-die finals in a row against East Perth, West Perth and South Fremantle respectively to reach their first ever WAFL grand final. In the grand final, Peel defeated Subiaco by 23 points to win their first WAFL premiership. Peel's midfield had too much running power and grunt inside for Subiaco, with Docker Connor Blakely winning the Simpson Medal on the back of 38 possessions. Fellow Docker Ed Langdon was also an important contributor with 39 disposals, eight marks and a goal.

Peel were a foundation member of the WAFL Women's competition in 2019. The club recorded their first senior women's premiership in the competition in the 2020 season.
