Miller returned to Cronulla in 1986 a more mature player, and after a slow start to his second stint with the club, by 1988 Miller had become one of the most dominant players in the ARL. He had the ability to consistently offload and send players into gaps (despite being small for a forward at around ), and was at the helm of Cronulla winning fifteen of their last seventeen home-and-away matches, and claiming the club’s first minor premiership. Despite not playing for New South Wales against either Queensland or Great Britain, Miller's club form was enough that selectors did not ignore him for the Test against Papua New Guinea. In a world international rugby league record 70–8 win, Miller "launched countless raid on the Kumuls' line" and scored a try. He also played in the World Cup final against New Zealand, remarkably scoring a try once again, and in between was named as Man of the Match versus a "Rest of the World" team.
