Perth Glory can confirm that Joseph Mills, Andreu Guerao and Jeremy Walker have all departed the club.
Defender Mills spent two seasons in the West, chalking up a total of 44 appearances and scoring one goal.
Spanish midfielder Andreu, meanwhile, was recruited for the 2017-18 campaign, during which he made 13 starts and was introduced from the bench on a further four occasions.
Walker was also brought in last year, initially on a short-term injury-replacement contract which was later extended to the end of the season.
The former Melbourne Heart full-back made the first of his 13 starts for the club against Newcastle in Round 2.
“On behalf of everyone at the club, I’d like to thank the three players for their efforts and wish them all the very best for the future,” said Glory CEO Peter Filopoulos.
