The Australia international confirmed his retirement tonight on Radio SEN in Melbourne.
"Obviously, I've hung up my boots internationally after the World Cup," Moore said tonight. "And as far as club football, I can tell you now, that's it. That's enough.
"I'm now taking my coaching badges and looking at that as a future career."
Moore added: "I think I could still play for a couple more seasons. But I can only see hurt for me in the future if I was to do that."
Former Gers captain and Newcastle United defender Moore's final game was Australia's 1-1 draw with Ghana in South Africa last week.
