Despite a lack of game time during the 2005 Super 12 season—he was suspended for six weeks after being found guilty of trampling on fellow All Black Richie McCaw during the game between the Blues and Crusaders—Williams was chosen to start in the opening Test of the All Blacks season, a 91–0 rout of Fiji, during which he scored his second international try. His third came two weeks later, in the first Test against the touring British and Irish Lions, a game in which he dominated the line-out, winning the ball several times on the opposition's throw, most effectively in the 24th minute, when, having caught the ball on a Lions' defensive line-out, he spotted a gap in the opposing line, darted through it and, shaking off an attempted tackle by the Lions half-back, Dwayne Peel, drove over the goal-line for the All Blacks' first try of the match. He started in all three Tests against the Lions, and scored his fourth international try in the final Test, when Dwayne Peel fumbled a grubber kick from Luke McAlister, and Williams pounced on the loose ball in the in-goal area. He started in all four of New Zealand's matches in the 2005 Tri Nations Series and came close to scoring another try in the last game, against Australia, on his home ground, Eden Park, but, after winning the ball at an Australian line-out and making a 20-metre break, his attempted grubber kick was wayward. He did, however, create the second of wing Doug Howlett's three tries in the game when, from within the Australian 22, in front of the posts, he executed a fine cross-field kick that Howlett caught on the far right of Australia's in-goal area for an easy touch-down. In 2009 Williams released his biography "Ali: Tall Book of Tales",It was during this time in which he spoke of an incident involving Clint Brown then TV anchor for 3 News who was stripped naked by Williams and members of the All Black team and had his eyebrows shaved off after becoming heavily intoxicated on a FLIGHT from South Africa to Australia.
