At the fake pit stop, teams get sent back to Sydney with the clue "To Set to Sail." The sisters and the BFFs work together to locate it, an anchor sculpture. There, they sign up for the first flight to Broken Hill, about 680 miles from Sydney. "I definitely think teams underestimate us because Zev has Asperger's," BFF Justin says. "I think that is going to work to our advantage."
Joining that first flight are the cheerleaders, mom and son, and the pink and black attack. Dad Mel struggles with the physicality of the race, almost passing out, which reduces son Mike to tears, but they make it onto the first flight. Everyone else is forced to go on the later plane.
Meanwhile, the cowboys get to the pit stop last, making many "Oh my gravy!" and "Son of a buck!" exclamations along the way. But the race is still going, so there's no elimination. Their bad luck continues when they can't find the sculpture. They finally hit it at night and secure their spots on the second flight, which leaves in the morning.
At Broken Hill, teams find out they have to go to the Living Desert, a barren landscape in the Outback. "So we're in the Outback," Zev says. "There are not a lot of steakhouses." Others start getting into the game despite there not being any blooming onion stop-offs. "A kangaroo can run faster than your driving, Kisha," trash-talks dad Mel, who's obviously feeling better. At the Living Desert, they hit a detour.
For this detour, teams must choose between two aboriginal customs, spirit world or natural world. In spirit world, racers use traditional materials to create a mosaic, and then do a dance on it to raise the ancestral spirits. In natural world, they make territory markers using a natural paint that they spit out onto a canvas. All of the teams must not like putting paint in their mouths, because they choose spirit world and seem to show up simultaneously to do the art project.
Unfortunately, the engaged couple got a U-turn in the last episode, so they have a big disadvantage in having to do both detours. But the dad-daughter team are bickering like an old married couple—but in both English and Chinese—and lagging.
The BFFs are the first to do a dance on their mosaics. Their next clue directs them to the home of the magpie, which is the Central Football Club back in Broken Hill. There, they find out that they have to dress up like a pack of crazy-looking kangaroos with bouncy shoes and are only left with a periodic table of elements with two elements highlighted.
The BFFs and the mom-son team find someone with a smartphone who deciphers the puzzle, telling them they are streets. Kent reps for the attack and knows the elements off the cuff. Mom Margie loses a 'roo foot cover, which forces her team to backtrack.
The two dad-daughter teams pair up, but it's a disaster. Dad Ron doesn't want to listen to Ms. Kentucky, who is running all over the place. "Why are we following them? She's hysterical," Ron says. So they break off on their own, which ends up being a mistake.
At the pit stop, Junction Mine, the BFFs snag first and win a trip to Cancun. The Globetrotters come in second, and the cowboys get some redemption with third place.
The dad-daughter team just makes it second to last. "Sometimes in the heat of the moment it's still difficult for me not to get too domineering," Ron admits. The engaged couple aren't as lucky and get eliminated. "Rather than the last time we got U-turned, this was our own fault," Kris says. "We basically won the lottery twice—we didn't win any money, but the experience of this, it's the opportunity of a lifetime, and I'd do it again in a heartbeat."
Teams head to Japan, and there's some mud-slinging—literally. The cheerleaders have a "gamechanging setback" that involves a possible accident.
