The new Hearts signing made his international debut at the beginning of this month in a friendly victory over Jordan.
The 23-year-old impressed enough to keep his position in the team for the crucial matches in World Cup qualifying against the United Arab Emirates and Peru.
He was awarded man-of-the-match in the latter fixture as the Socceroos won on penalties to advance to the finals in Qatar.
Fellow Socceroos star Bailey Wright couldn’t help but be impressed by his younger team-mate as he heaped praise on Rowles and fellow Hearts defender Nathaniel Atkinson.
He said: "Kye, stepping in, making his debut the other day and playing in these games, it's a credit to him.
"He's taken it in his stride. His maturity, his quality, he's got a big future ahead of him and so does Nath. We've got a lot of good young players coming through."
