In a video message to an awards ceremony held by a global network for Australian expats, Advance.org, Morrison said they had carried a "very heavy burden" over the past year and a half.
"I know for Australians overseas, it has been a very difficult and frustrating time," he said.
"It's tough, living through a pandemic, and being separated from your family, and that's brought its own heartbreak.
"Life's moments missed that you will never get back. Zoom can't do justice to these moments."
