McQualter began the 2008 season quietly on s rookie list, but began to turn in several solid performances with St Kilda's affiliate in the Victoria Football League (VFL). With his continued good form McQualter was temporarily elevated off the rookie list and selected to play against Sydney in Round 12. He cemented his place in the senior team after several tagging jobs and played nine consecutive games, a personal best for McQualter at the time. He played his first AFL final in the 2008 1st Qualifying Final against Geelong. McQualter was promoted back onto St Kilda's primary list at the end of the 2008 season.
