Fremantle's Joel Hamling and Sam Switkowski have both signed deals to remain at the club, with Hamling signing a four-year extension that will keep him in Perth until at least the end of the 2023 season.

The 25-year-old defender was coming out of contract at season's end, but has now secured his future.

“I’m honoured to be a part of the club for the next five years and really getting stuck into my role,” Hamling told fremantlefc.com.au.

“I’m feeling really good about my footy. I’ve had a full pre-season this year. It’s season eight for me now so I’m really comfortable in my body and my ability.

“I’m just looking forward to round one, just getting stuck into it again.

“It’s another exciting year for us, we’re very optimistic as a team and we’re looking to build each year.

“We’ve simplified our game plan, made it a lot easier, we’re going to go forward, attack the ball and try and kick some more goals.”

Switkowski has put pen to paper on a two-year extension, which will see him remain a Docker until 2021.

The 22-year-old has played two games for the club, but can't wait to return to the side.

“It’s just great to be able to extend and take a little bit of pressure of this year and just focus on my footy. Knowing that I’ll be here for at least a couple more years is really exciting,” Switkowski told the club's website.

“I’ve had a really good pre-season, probably my best pre-season for a long time. I had a little bit of a setback a couple of weeks ago but it’s very minor and the recovery is going really well. Hopefully, I should play a big part in 2019.

“We have such a young team and it’s super exciting seeing the guys starting to step up with a little bit of experience.

“We saw in the JLT, Andy Brayshaw, Adam Cerra, Bailey Banfield, those sort of guys stepping up. It’s great that there’s a lot of opportunity for us young guys.

“I think there’s no limit with what we can achieve this year and in the future.”
