As the first of Oprah Winfrey's audience members touch down in Sydney, Prime Minister Julia Gillard has announced she will also appear on the show.
Oprah will be arriving by private jet, but there is speculation that she will not arrive until tomorrow.
Final season
The talk show host is wrapping up her 25th and final season with a trip Down Under, where she'll film two episodes at the Sydney 'Oprah' House later this month.
Australia will also be the focus of a third episode of The Oprah Winfrey Show, which will be compiled cataloguing their travel experiences.

Tourism bonanza
Federal Tourism Minister Martin Ferguson has again lauded the decision to choose Australia for Ms Winfrey's big finale, in which 12,000 Australians will get to watch filming live.
"Oprah is a household name, not just in the United States but in the 145 countries where the show is broadcast," he said in a statement on Tuesday.
"That Oprah has chosen Australia as her Ultimate Adventure destination sends a powerful message to her millions of fans around the world.
"Most importantly, it shows that a holiday Down Under is not just do-able but very desirable."
The show was also a reminder to Australians to embrace domestic travel, Mr Ferguson said.
He extended a warm welcome to Ms Winfrey's audience and her cast and crew.
The episodes are due to air in both the United States and Australia in January.
