The 25-year-old has defied a mass player exodus at the club by agreeing a five-year deal, which will extend his contract until 2024.
Swallow said the decision to re-sign with the Suns was due to his family embracing the Gold Coast lifestyle.
“The Gold Coast community has really embraced us in my time up here, me and my partner Georgia love living on the Gold Coast, it’s home,” Swallow -told the Suns website.
“We’ve got a young family, we’ve got a business, we’re really settled here.”
Swallow has played 117 games for the club since being recruited with pick 1 in the 2010 National Draft.
The midfielder has seen former teammates Dion Prestia and Josh Caddy win premierships at Richmond, while fellow 2010 recruits Tom Lynch and Steven May switched to the Tigers and Melbourne in the off-season in the attempt to experience on-field success.
Swallow believes the Suns are on the right path to achieve their own success with a young side driven to succeed.
“We’ve got a young list, that’s really tight, and driven for success,” Swallow said.
“The club is well placed, some good appointments in the coaching area and fitness staff and going forward is really exciting and I can’t wait to get stuck into it.
“Everyone wants to see the Suns be successful and it’s going to take a collective effort from everyone involved to get there.”
