Chris Hemsworth showed off his fit physique at the Park Hyatt Hotel pool in Sydney yesterday. He went shirtless for a dip in the water, though he covered up to take pictures with an older guy. Chris is in his native Australia to premiere Snow White and the Huntsman, which already had a huge opening in the US. His costar Kristen Stewart just arrived Down Under yesterday afternoon and will be by his side for the upcoming red-carpet event. Chris's promotional travels meant that he missed spending Father's Day with his newborn daughter, India. He wasn't without family and friends however, since Chris was greeted at the airport by his grandmother and hit the beach with a pal to go surfing shortly after his arrival.
