Jeremy Walker will be continuing his spell with Glory after his injury replacement contract was extended.
The 24-year-old has acquitted himself superbly since arriving in the West back in October, making seven starts and establishing himself as a key part of the defence.
And with Marc Warren not expected to return from his ankle injury until the New Year, Glory's Head of Football Jacob Burns was pleased to confirm that Walker will be remaining on board.
"Jeremy has really impressed us with his professionalism on and off the pitch," he said.
"He was thrown in at the deep end on debut against Newcastle in Round 2, but responded well and has done a terrific job for us ever since."
Unfortunately, however, Mitch Mallia has parted company with the club following the end of his injury replacement deal.
The Sydneysider debuted alongside Walker against the Jets, made a further five substitute appearances and found the net in the Round 8 win over Melbourne City.
But with Joel Chianese now fully recovered from his cracked collar bone, the difficult decision was made to allow the winger to return to his native Sydney.
"It was a tough one," confirmed Burns, "because Mitch, like Jeremy, has done really well since he's been with us.
"But hopefully his performances for us have put him in the shop window and he'll be snapped up elsewhere.
"We'd like to thank him sincerely for all his efforts and wish him all the very best for the future."
