In 2006 he started in all but one match for the Waratahs who made it to the finals of the 2006 Super 14 season. He was subsequently named in John Connolly's Wallaby squad. Later that season he injured his shoulder and underwent reconstruction surgery in November 2006. Although missing most of the 2007 Super 14 season through injury recovery, Vickerman returned to the Test scene in a test match against Wales coming off the bench, and cemented his place back in the Wallaby starting line up for the Wallabies 2007 Rugby World Cup squad. Vickerman raised his 50th Test cap against Wales during the 2007 World Cup, but managed just three appearances during the 2008 international because of another shoulder injury he sustained in the 2008 Super 14 final.
