Moore returns to Roar
The 39-year-old was the club's first marquee player in 2007 and is a former captain.
In much-needed good news for the Roar, two-time Gary Wilkins Medallist Moore returns under coach John Aloisi.
"Craig has a wealth of experience in football and a first-hand understanding of what it means to play for the Roar,” Aloisi said.
"He will work closely with me as football operations manager.
"His football knowledge and his love for the club will be invaluable as we transition to a new era and rebuild the Roar to challenge for honours again."
The former Rangers, Crystal Palace and Newcastle United defender played for Australia 52 times.
He was a player mentor with the Socceroos in recent years and travelled to last year's World Cup with the squad.
"It great to be back at the club at such an exciting time,” Moore said.
"I aim to support John and oversee the structure and operations of the club’s football department."
It comes after revelations earlier on Tuesday that the club is yet to pay players and staff in June.
Payments were due on the 15th of this month.
However, the club's owners are expected to invest $3.5m – although that has not yet been received.
