Thomas has signed a three-year contract extension with the Eagles to remain there until at least the end of the 2027 season.
Already contracted for next season, she is coming off a breakout season that saw her selected for the All-Australian team - the first West Coast Eagles AFLW player to do so.
The 20-year-old solidified herself as a stable backline player last season and is looking to continue her development and lead the club to success in the near future.
“It's really exciting to be staying at the club for another four years,” Thomas said in a media statement.
“I'm looking forward to what we can achieve over the next few years, with some exciting young talent coming through, the girls make hard work easier, we're a really tight-knit group and I just love being around them.
“I'm keen to just keep playing my role for the team, however that might look, in whatever position, and develop my craft, get fitter, faster and stronger for the next season, and then as a team, we'll hopefully get a few more wins on the board, which I'm confident that this group can do.”
Just like Thomas, Courtney Rowley is already contracted for the 2024 season but has decided to sign on for a further two seasons.
The game saw her end with 18 touches, eight contested possessions, three marks and two tackles, with 232 metres gained.
However, she will unfortunately spend the off-season in rehabilitation - working through a 12-month recovery - after requiring surgery on an ACL injury she sustained in Round 10.
“I'm super happy and super keen, I honestly wouldn't want to be playing my footy anywhere else,” Rowley said.
“I love it here, I love the girls and have such a love for my team, we have such a good, young group and there's a lot of us girls who are really committed to sticking together.
“The club as a whole has a lot of belief and trust in me, so that also made the decision to extend so much easier.
“Next year will just be getting through my rehab and working really hard to get back into the team and building up my strength, and as a group, I'd like to see us win some more games and continue working hard together to reach our goals.”
