Nicole Kidman and Keith Urban interview together on Oprah Winfrey Show: Oprah Winfrey is not a woman to do things by halves, so it's no surprise that her Grand Finale in Australia was spectacular. Joined by Bono, Hugh Jackman, Olivia Newton-John, Russell Crowe, Nicole Kidman and Keith Urban, the talk show queen held the finale at the Sydney Opera House. Viewers watched the dramatic moment when Jackman injured his eye after zip-lining down onto the stage from the top of Sydney Opera House. The actor needed stitches to close a nasty gash below his right eye after he braked too late.

Jackman says: 'The brake was stopping so quick [in rehearsal]. 'So, I'm coming down, and I see everyone ... I see you, and I went, "Probably time to brake now. Oh, it's not going to stop." Bang! Totally my bad.'He then introduced Oprah to Vegemite, which she said she liked. Bono appeared on stage to talk to Oprah about his career, and how he has stayed relevant for the past 30 years.

'You have to dig very deep when you're going to the studio, and you have to try and surprise yourself first,' he said. 'If you do that, I think you can surprise your audience and that's what keeps you relevant.'Nicole Kidman and Keith Urban also gave their first-ever interview as a couple as they joined Oprah on stage. And they admitted that although they live in Nashville now, they try to come back to Australia whenever they can.

'When we're here, we tend to enjoy ourselves,' Nicole said. Australian actress Olivia Newton-John also appeared in the finale, and showed off the infamous black leather trousers she wore in Grease 32 years ago.

'A body was in here!' Oprah says. 'Look at this.''Just to think it was mine once too,' Olivia says. And the audience were in for a big surprise when Oprah gifted them all with beautiful diamond necklaces. 'Guess what, my Aussie friends, the folks at the mine did a little more digging and found 6,000 more necklaces!'

The white gold and diamond necklaces are provided by Rio Tinto's Argyle Diamond Mine, a mine in Western Australia that's home to the world's largest treasure trove of colored diamonds. The open-air spectacle, which topped off Oprah's Ultimate Australian Adventure, ended with a rousing rendition of 'I Still Call Australia Home'.
