Phillip Island did not feature on the Supercars calendar in 2004 and then from 2005 to 2007 the circuit hosted the Grand Finale, the last round of each season. In 2005, Russell Ingall secured his first championship win at the event, having finished runner-up in the championship four times previously. Going into the 2006 event, Rick Kelly led the championship by a small points margin over Lowndes. Following the first two races, in which Lowndes complained of being unfairly held up by Kelly's teammates, Kelly and Lowndes were tied on points. A controversial incident in the third race saw Kelly make contact with the back of Lowndes, sending Lowndes and Kelly's brother Todd into a spin. Lowndes was stranded in the middle of the track and was hit by Will Davison, sustaining steering damage which caused him to finish in thirty-first place. Despite receiving a drive-through penalty for his role in the incident and finishing eighteenth and a protest from Lowndes' team, Kelly was crowned champion. The event decided the championship again in 2007, with Garth Tander and Jamie Whincup battling for the title. Tander won the event, winning two races, and secured the championship by two points over Whincup.
