UPDATE 1.10pm: Patrick Long is back in the Competition Motorsports team and in 11th place after 190 laps of the Bathurst 12 Hour.

After 148 laps, Campbell was in 11th place but moved up to ninth after 154 laps, and 3rd after 161 laps.

Warwick driver Matt Campbell is one of the team's four drivers.
