Naomi Watts and Liev Schreiber took advantage of their trip away from cold NYC to hit the beach in Sydney with their sons Sasha and Samuel yesterday. The family of four is off on a vacation down under visiting Naomi's native Australia. They arrived there about a week ago, just in time to celebrate Australia Day at a family barbecue. The getaway comes during a break in work for both Naomi and Liev. She's gearing up for a return to the big screen in The Grandmothers with Robin Wright, as well as While We're Young with Ben Stiller. Liev, meanwhile, has multiple projects to promote. He's got Mental on the way this year, as well as The Reluctant Fundamentalist, opposite Kate Hudson, coming out in 2013.
