Two new rules were made for the Season 10 installment of the race: The Intersection was introduced, a task where two teams were required to work together until otherwise instructed. If no other team was available when one team read the Intersection clue, they were required to wait for another team to show up before proceeding. The Intersection was also in conjunction with a Fast Forward, with the first team pairing to win to earn the Fast Forward for both teams; Instead of the previous money and baggage penalties for coming in last place, the last place team in a non-elimination leg became Marked for Elimination meaning that unless they place first in the following leg, they receive a 30 minute penalty at the mat, possibly allowing teams finishing behind them to overtake them in the final placings for that leg.
The world is waiting for you. Good luck... travel safe... go!
When the teams are travelling from Argentina to Mozambique in the fourth episode of the All-Stars series, Phil Keoghan's voice-over states that there are no international flights out of Ushuaia Airport. However, at what the on-screen caption claims is Ushuaia Airport, a Qantas plane is clearly visible. Qantas is Australia's main international airline and would not be present at a solely domestic airport in Argentina (Qantas do, however, fly to Buenos Aires, so the scene was presumably filmed at Buenos Aires' international airport).
In the opening credits, quick shots of countries and other clues are shown, hinting where the race will go.
