The 30-year old midfielder, who is often deployed at left-back for the Socceroos, has returned to former club Brisbane Roar following stints with China's Changchun Yatai, Scotland's Rangers and South Korea's Busan I'Park with some critics suggesting it could be a negative move.
But McKay has revealed that Socceroos boss Holger Osieck isn't too worried about his selection hopes despite being back in Australia's domestic competition.
"I had a good chat with Holger and he was very positive," McKay said.
"He's got a lot of time for the A-League and you could see that (Melbourne Victory's Mark) Milligan came in and did a good job for the three qualifiers this year and I broke into the Socceroos through the A-League.
"You want to be playing competitively as close as you can to the World Cup and I'm sure the Roar will be there at finals time.
"Ever since I left I was thinking about the day I would come back. I felt very wanted here and it's a club that's going places again.
"It's improved since I was here two years ago and I want to be a part of the again."
