The ex-Bomber played just three senior games for the Power this season as the club stormed into September as a top-four seed, with Fantasia's Alberton future uncertain beyond this year.
The 28-year-old, who has battled injury issues since crossing the border from Tullamarine at the end of the 2020 season, remains uncontracted for the upcoming 2024 campaign after his three-year Port Adelaide deal expired at the end of this season.
According to Fox Footy reporter David Zita, Fantasia is expected to meet with GWS on Thursday as the Giants look to occupy two rookie list spots ahead of the pre-season.

Fantasia shot down links to a potential Essendon return in July, stating he wanted to continue his footballing journey with the Power.
However, injury issues, combined with a lack of senior opportunity under Ken Hinkley, mean the picture may look a little bit different for the South Australian forward as the 2024 pre-season nears.
The Giants, meanwhile, headed by list boss Jason McCartney, are understood to be considering multiple possibilities regarding filling that pair of vacant rookie spots.
One of those possibilities includes offering a rookie-list lifeline to off-contract veteran Lachie Keeffe, who played an integral negating forward role during GWS' finals run this year.
The Giants are also understood to be interested in luring Adelaide Crow Elliott Himmelberg to Western Sydney to join forces with brother Harrison, who recently penned a long-term extension in the Harbour City.
Meanwhile, regarding likely exports, ruckman Matt Flynn is widely expected to depart the Giants' ranks in favour of the West Coast Eagles, where a first-choice ruck role seems up for grabs.
