St Kilda appears set to swoop in late for Ballardong Noongar delisted free agent Sydney Stack, who has attracted Fremantle's attention.

Stack returned home to Western Australia in the offseason since Richmond's shock call to cut the Indigenous talent after four seasons and 35 AFL games.

The 22-year-old had taken up an offer to train with Perth, the same WAFL club from which the Demons junior was signed during the preseason supplemental selection period.

That last-ditch recruitment method could again save the agile utility's AFL career after being largely ignored across the trade period and the ensuing draft.

Paul Peos, Stack's manager, said his gifted client is focusing solely on an AFL career again after criticism levelled at his professionalism, fitness and commitment.

"Hopefully someone steps forward and provides him with an opportunity," Peos said.

"He's pretty open to going anywhere for a chance."

St Kilda have begun to engage in ongoing conversations with Stack over filling one of two remaining senior spots on its list.

The directive in the conversations are believed to ensure the Saints' fitness programs are strenuously followed 3,500 kilometres away from the Moorabbin training base.

Stack's signature would bump up the club's strong First Nations' representation back to eight players.

After the departure of Ben Long to the Gold Coast and the retirement of Paddy Ryder, St Kilda drafted Indigenous athlete Issac Keeler from SANFL club North Adelaide via South Augusta.

Fremantle is also one of seven clubs, including Stack's former Tigers, to still have one place to fill for next season.

AFL recruitment guru Michael Ablett has been very vocal that Stack's experience and finesse is a perfect fit for the Dockers amid a loss of a number of experienced players.

Part of that advice from the former Western Australian talent pathways manager for Fremantle's recruiting scouts comes from Stack settling better back in his home state.

Born in Northam, north-east of Perth, Stack was shuffled around family and different relatives growing up and lived in five different households before turning 17.

"Do Freo explore someone like a Sydney Stack that can come in?" Ablett told The West Australian.

"We know Syd has had his challenges and fallen out of favour a little bit for some of his errors off the field, but his on-field stuff is electric."
