Nicole appeared on the Oprah Winfrey show with husband Keith Urban and revealed she will show the US talk show queen around Sydney.
The Aussie couple also revealed another winning audience member will accompany them on the trip.
Nicole, 43, told Oprah she is travelling with Keith to her hometown Sydney to meet up with Oprah and 300 lucky audience members at the Sydney Opera House.
During her first trip to Australia, Nicole suggested that Oprah spend a day at the beach.
'While filming Moulin Rouge, I would go to Bondi Beach, go for a swim, have some breakfast, and then go to work,' she said.
Oprah's Australian adventures air January 17 in the US.
