Obsolete Reynard chassis were replaced with bespoke Lola units, and the team signed Canadian Champ Car veteran Alex Tagliani and Australian Formula 3 driver Marcus Marshall for the 2005 season.
By Team Australia's homecoming at the 2005 Surfer's Paradise race, they had announced that a third car would be run for Australian international driver Will Power.
The team ran their third car again in the season finale at Mexico, where newly crowned Atlantics champion Dutchman Charles Zwolsman made his debut.
In 2006, Team Australia's commitment extended not only to two Champ Cars, but a two-car Atlantic squad, all aimed at fostering young talent.
The team showed fantastic pace at the opening round at Long Beach, with Tagliani and Power running third and fourth respectively before a forced error dropped him down the order.
Craig Gore expanded the Team Australia stable of global motorsport interests with a partnership with Wood Brothers/JTG Racing that included the naming-rights sponsorship of Marcos Ambrose's entry in the NASCAR Craftsman Truck Series in 2006.
The sponsorship was weaved into a nationwide marketing campaign designed to promote quality Australian and Australian-themed products and Australia as a tourism destination.
