Later that year he joined the Socceroos on an extensive world tour, playing matches in China, England, Scotland and Italy.
FFA chairman Frank Lowy issued a statement saying he was saddened to hear of Gray's passing.
"Ian gave great service to the Socceroos, playing 35 matches over nine years and he was a very respected teammate and a friend to many," Lowy said.
"He was also an active former Socceroo and a great ambassador for football.
"On behalf of the Australian football community I would like to send my condolences to Ian's family."
