Liam, 29, was seen hanging out with older brother Chris Hemsworth at his luxe $4.3 million Byron Bay beach house in Australia.
Chris, 36, and the Isn't It Romantic star took a trip into town and got some frozen yogurt.
Liam looked forlorn as he strolled around the city. He kept his head down in a light brown hoodie, white sneakers and black cuffed jeans.
According to reports, Liam admitted that things have been tough since Miley, 26, and him went their separate ways.
"You don't understand what it's like," he said told reporters about the breakup. "I don't want to talk about it mate."
Shortly after the news of their split hit the airwaves, photos of the Disney Channel alum kissing The Hills: New Beginnings star Kaitlynn Carter in Italy surfaced.
