Senior GWS trio Stephen Coniglio, Josh Kelly and Kieren Briggs have all required surgery since the cessation of the club's 2024 campaign.
Coniglio required facial and shoulder surgery in the wake of his latest season, having suffered a heavy collision in the Giants' final game of the year against Brisbane.
A marking contest involving Lions captain Harris Andrews left Coniglio unable to return to his side's semi-final against the eventual premiers in September, with the veteran midfielder since requiring an operation on his face.
Coniglio has also undergone shoulder surgery after an injury-hit year that saw him play just 15 games in 2024.
The former GWS captain is scheduled to start running at training again next month.
Fellow onballer Kelly has undergone a hip arthroscope in the off-season and has since resumed running as part of his rehabilitation.
Briggs will be sidelined until closer to the new year after he had post-season surgery to tidy up cartilage in his knee. Briggs is expected to resume running within the next 5-7 weeks.
GWS players are scheduled to return for pre-season training in the coming weeks as the club looks to bounce back from their straight sets finals exit from two months ago. The Giants' first-to-fourth-year players will commence their programs on November 25.
A 2025 start date and further fixture details are expected to be announced later this month.
