Nicole Kidman and Keith Urban reported to the airport in Sydney this morning with their daughter Sunday. They're on the move after a fun visit that included a casual day spent checking out a play at the city's famed Opera House. The Kidman-Urban clan were Down Under enjoying the sun along with another famous family — Naomi Watts and Liev Schreiber have also been taking advantage of the Australian sunshine with sons Sasha and Sam. Nicole is currently focused on enjoying the holidays during a break from promoting her new movie Rabbit Hole, which opened here in the US, in limited release, last week. Nicole and her family have more to celebrate than Christmas, as her sister Antonia welcomed her fifth child on Dec. 11!
