While Oprah is meeting koalas, the crew and celebrity chef Curtis Stone are putting the finishing touches on a bash at Whitehaven Beach, one of the most beautiful white-sand beaches in the world. "It's the first time Oprah's going to be with any viewers in Australia," Sheri says.

Once the viewers are on the beach, Oprah is set to land in a helicopter. "This whole beach party is all timed out to perfection," co-producer Lindsay says. "The helicopter has to land at the right time. The viewers have to be on the beach. We have to bring barge upon barge to get them over there."

Unfortunately, the timing isn't quite right. "Up in the sky, I see a helicopter," Sheri says. "I go, 'Oh my God, Oprah's here and the viewers aren't on the beach yet.'"

Watch how the crew saved Oprah's grand arrival.

"That's a great party entrance, I must say," Oprah says. "If you've got to enter a party, that's the way to go."
