Oprah was filled with surprises each day, and nobody knew what was going to happen from one stop to the next. One day, it turned out they got to attend a U2 concert with Jay-Z as the opening act.

“You’re my book-club girl, Jocelyn!” Oprah Winfrey announced as Jocelyn Kelley from Marblehead, Mass., approached to say hello.


Kelley is still in shock that Oprah recognized her among 302 Oprah fans gathered in Sydney, Australia, for 10 days. Kelley, a book publicist at Kelley & Hall, was inspired by Oprah’s book club enough to start her business and Skype with the host on-air about Oprah’s book-club picks.


Kelley works in the family business with her mother, Gloria, who accompanied her daughter Down Under. The two were selected to join 300 other Oprah fans lucky enough to score a trip to Australia with Oprah, as part of her talk show’s farewell season.


Still beaming from time spent with Oprah in Australia, the Kelleys hold a memory they’ll cherish forever. It didn’t all go according to plan, they report, but they were all too willing to go with the flow.


As announced on the “Oprah Winfrey Show,” John Travolta was supposed to pilot the airbus to take the whole lot, including Oprah, to Sydney on Dec. 4, but Travolta had to bow out because of the Nov. 23 birth of his son, Benjamin. Oprah herself had to take a later flight because she was being celebrated at the annual Kennedy Center Honors lifetime achievement awards.


For those curious to know what went on Down Under, highlights of the Ultimate Australian Adventure are being aired on the Oprah show Tuesday, Jan. 18, through Friday, Jan. 21.


And for those curious about what happened behind the scenes, read on.


“It was a media onslaught, unlike anything I’ve ever experienced,” says Gloria Kelley.


From the moment they stepped off the Qantas plane, they experienced what celebrities endure in the public eye on a daily basis. The Australian press wanted to know Oprah’s itinerary, her every move. But the Kelleys didn’t have the answers. In fact, throughout the entire 10 days, they never knew what they would do next — until they received instruction.


One day, they were given a boxed supper and were told to take it with them onto a bus. They boarded, never knowing where they were headed. Turns out they got to attend a U2 concert with Jay-Z as the opening act. Oprah was filled with surprises each day, and nobody knew what was going to happen from one stop to the next.


Jocelyn Kelley had meant to blog each day for the Boston Globe, but when Oprah’s producers found out about this, the idea was nixed. All was kept hush in preparation for the unveiling that will occur on the Oprah Show this week.


“The element of surprise was there every day,” says Jocelyn Kelley.


Although unapproachable to the media, once in Sydney, Oprah and Gayle King, Oprah’s best friend, were quite available to the 302 fans on the Adventure. In fact, they all stayed in the same Intercontinental Hotel.


Says Gloria Kelley, “Oprah is energetic and gracious,” while Jocelyn Kelley says she felt like she was “in the presence of something larger than life.”


Both Kelleys say there was lots of interaction with Oprah on the Adventure. Oprah attended many events in every area with the groups that spread out in accordance to their interests. Some spent time in the outback, while others, like the Kelleys, spent time shopping in Sydney.


Oprah would helicopter over to be with each group, but her attentiveness could be attributed to filming the documentary pieces she plans to air on the Oprah Winfrey Network, or OWN, as well as for the Oprah Winfrey Show. Highlights include celebrities Russell Crowe, Olivia Newton-John, Hugh Jackman and many more who showed up to thrill Oprah fans and be part of the Adventure.


Jocelyn Kelley says her favorite part of the Adventure was when she climbed the Sydney Harbor Bridge.


“It was a moment of reflection,” she says of climbing to the top and viewing all of Sydney.


Gloria Kelley, on the other hand, stayed behind with a few who didn’t enjoy the feel of the bridge’s height.


“I was sailing on a yacht, having lunch instead,” she says, laughing. To prove this, she calls up an image on her iPad of the boat in front of her, with Russell Crowe on board.


As if the trip weren’t enough, during their time in Australia, all 302 of Oprah’s guests received a gift from the talk-show queen. Each woman received a beautiful pearl necklace, the pearl encased in a silver “O,” with an inscription on the side to document the trip.


“It’s surreal now,” says Gloria Kelley, who is still amazed by the surf schools she noticed with 3-year-olds taking lessons, as well as the pools constructed in the ocean, walled off from sea life.


The shopping and the food were definite highlights for the Kelleys, who explain how you can go from the George Street shopping area and walk 10 minutes to the harbor, catch a ferry and be on a fabulous beach in 20 minutes.


“There were parties every night, like it was Carnivale,” says Jocelyn Kelley, who describes Sydney as “New York City and Hawaii combined.”


The Kelleys and Oprah’s 300 other fans received a personal goodbye on Dec. 15, many with grateful tears for being honored with the experience.


“I would go with Oprah again,” says Gloria Kelley, despite the 20-hour flight and the daily element of surprise.


Who knows? It could happen again. When it comes to Oprah, the audience has learned to expect the unexpected.
