OprahOprah Winfrey is known for her grand gestures -- especially on 'The Oprah Winfrey Show,' where she continues to give away fabulous gifts to her audience. And for the final season premiere of her syndicated talk show, she's gifting everyone in the audience with a trip to Australia.

"Because, after all, this really is my 25th season and this is really my last chance to do something really big," she explained, The New York Daily News reports.

There will be two episodes of 'Oprah's Ultimate Australian Adventure,' which will feature O's biggest fans down under, in places like the Sydney Opera House. The trip will happen this coming December.

"It's one of the places I've always wanted to visit, and who better to take with me on this trip of a lifetime than some of my most loyal viewers. My team has been planning this trip for almost a year and we are so excited," Oprah said in a statement.

After airing, Oprah tweeted that she was pleased no one let the news leak. "Audience -- it's unbelievable that you kept that secret all weekend!! Way to go mates," she wrote.
