• Enrico Toccacelo replaced Adam Khan at A1 Team Pakistan in Durban after the latter was injured in a practice session. As Toccacelo is not Pakistani, he was ineligible to score points for the team.
• A1 Team Indonesia was unable to participate in Australia as the team did not find a replacement driver for Ananda Mikola.
