Both players have asked the club to find them new homes, although Staker is contracted to the Eagles for 2010.
List and contract manager Steve Woodhouse told afl.com.au on Wednesday that the club was in negotiation with Seaby and Staker.
"Seaby (is) looking to go to Sydney and we're discussing that with his management ... the same with Staker, who has been up to Brisbane," he said.
"We're in discussions with them and we've got to work through that over the course of the next couple of weeks."
Seaby has played 102 games for the Eagles since his 2004 debut, while Staker has appeared in 110.
They played just 11 matches between them in 2009, though Staker was injured for the majority of the season.
The West Australian had reported that the Swans were showing significant interest in Seaby and that the 25-year-old had been offered a three-year deal.
West Coast coach John Worsfold suggested on Seven News last week that Staker could cross to the Lions in a deal that might see midfielder Bradd Dalziell return to Western Australia.
Young defender Matt Spangher has also not re-signed with the club although the Eagles are hopeful he will remain at West Coast.
