Hollywood's top talk show host Oprah will be filming her Australian episodes starting tomorrow but it remains to be seen whether the 24-hour strike by maritime workers will disrupt The Oprah Winfrey Show at the Sydney Opera House.

The Maritime Union members are meeting this morning to decide whether they will continue their protest for wage increase. The planned strike may disrupt the filming of The Oprah Winfey Show.

Today, Oprah Winfrey will take a cruise to Rose Bay after she conquered Sydney's famous landmark, the Sydney Harbour Bridge, a day before. As part her Ultimate Australian Adventure, Oprah and 249 people including her bestfriend Gayle King climbed the top of the bridge and were treated to bird's eye view of the harbour city.

Oprah and her audience already visited the Great Barrier Reef, Kangaroo Island, Uluru and the Yarra Valley. Last Friday, she made her only public appearance in Federation Square in Melbourne where she met with Australian Prime Minister Julia Gillard in the afternoon.

Oprah Winfrey's Australia visit has sparked a ticket frenzy among Australians,as 3000 people chosen by online lottery tickets, will be part of her audience in a two-episode show at the Opera House.

The eight-day trip trip to Australia and the two episodes will be the first Oprah Winfrey episodes to be filmed outside Oprah's home country United States. The episodes featuring Oprah's trip to Australia will also mark the start of the show's 25th and final season.

Oprah's ongoing trip in Australia is part of the country's tourism promotion with funding from the federal and NSW government. Tourism Australia, Qantas Airways, Chevrolet, Motorola, American Express and Telstra are among the Oprah's Ultimate Australian Adventure sponsors and partners, with Channel Ten as its Australian television affiliate.
