Today, Oprah Winfrey took a cruise around the harbour with Australian actor Russell Crowe and her 300 audience, in 20 yatchts. The cruise comes 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.
