Both Fiorini and Flanders have found themselves on the outer of Stuart Dew's best 22 at times in 2022, however have looked to hold down roles at AFL level across the past month.
Fiorini has amassed 76 games for the Queensland club since venturing from Victoria's northeast at the end of 2015, taken with the 20th overall selection in the National Draft.
The 24-year-old enjoyed a breakout campaign in 2015, before succumbing to several setbacks through injury and struggling to cement his role at the Suns.
Flanders, who joined Gold Coast as a first-round selection in 2019, has played 28 games across three seasons at the Suns, including the last six of this year.
He joins Fiorini in being signed at the Suns until the end of next year, with the pair having last inked new deals in the past two seasons.
However, despite their contractual status, rival clubs are understood to have made inquiries about both Flanders and Fiorini, who hail from Victoria.
The Suns have shown a willingness to part ways with contracted players in the last 12 months, with Brodie sent to the Dockers in a pick-heavy trade, while utility Darcy Macpherson was floated for a move to North Melbourne in a potential salary dump in the same window.
Gold Coast have managed a strong spree of retention signings in 2022, having locked away Ben Ainsworth (2024), Mac Andrew (2025), Connor Budarick (2025), Elijah Hollands (2024), Ben King (2024), Jack Lukosius (2026), Touk Miller (2027) and Ned Moyle (2024) to new deals this year.
In-form forward Izak Rankine remains the big fish yet to recommit, however the South Australian livewire is expected to re-sign for 2023 and beyond.
Gold Coast will again have a tough task in holding off circling rivals next year, with the likes of Rowell, Anderson, Jeremy Sharp and Alex Sexton among those with contracts expiring at the end of 2023.
