Walters returned to Queensland in 1990, signing with the Brisbane Broncos to play alongside his twin brother Kerrod once again. Up until 1990, Wally Lewis was the Broncos' first choice for the position, but coach Wayne Bennett moved Lewis to lock and Walters to five-eighth. This was because of Walters' darting runs and deft passing. That year he won the Broncos' "Player of the Year" award. Walters played from the reserve bench in all three games of the 1990 State of Origin series. He also made selection for the 1990 Kangaroo tour of Great Britain and France with twin brother Kerrod, playing in several tour matches against local sides but no test matches. The following year Walters was again selected to play in all three State of Origin matches for Queensland from the bench. He made his test match début on the 1991 Kangaroo tour of Papua New Guinea, where he and his brother Kerrod became the first twin brothers to play rugby league for Australia.
