The Oscar winner shared a picture of his vegemite on toast breakfast and a glass of water, hinting that he's over the worst. He also included a little toy kangaroo and a cute koala bear in the photograph in homage to those who have helped take care of him.

He captioned the image: "Thanks to the Helpers. Let's take care of ourselves and each other. Hanx"

Fans responded to wish him and Rita well while others joked about the generous helping of spread on his toast.

"That's a lot of vegemite even for Australian standards. But hey enjoy!" said one.

"Mr Hanks. You are doing it wrong. That's way too much Vegemite," wrote another.

Earlier in the week, Tom and his wife Rita posed for a smiling selfie as they remained in isolation.

Hanks had announced that the pair had contracted the virus in a statement, as they became the highest profile celebrities to have fallen ill with the virus.
