Central Coast Mariners have boosted their defensive options with the signing of free agent Ruon Tongyik on a two-year deal.
Alen Stajcic snapped up the young centre-back following his release from Hyundai A-League rivals Brisbane Roar.
Tongyik, 22, joined the Queensland club from Western Sydney Wanderers in February and made eight appearances.
He previously had a stint with Melbourne City and follows ex-Wanderers utility Giancarlo Gallifuoco in moving to Gosford.
"I am delighted to be joining the Central Coast Mariners for the next two seasons," Tongyik said.
"The Mariners have a proud history in the Hyundai A-League, and I'm looking forward to helping the club get back on top next season.
"I can't wait to get working with Alen Stajcic as a boss.
"He has an excellent coaching record and reputation, and I truly believe I can develop as a player under him."
Stajcic, who earlier this month inked a three-year contract to become Central Coast's full-time head coach, revealed himself as a long-term admirer of the Olyroos defender.
"It's really exciting to bring a young player like Ruon to the club," he said.
"Over the past few years he has shown amazing potential to be a fantastic footballer and has a real drive to succeed.
"I've been watching him for a while, and I'm sure he will be a great contributor to our team on and off the field."
