The actor posted the pictures to his Instagram account.
He captioned the post: "Australia Day at the kids' school raising money to send over because of the bush fires.
"Hollie is made up because she's got my bottle from I'm A Celeb, Tom on the other hand is fuming because the tassels from the hat keep whacking him in the face.
"Let's hope they raise a decent amount of money today though as it's horrible what's happening in Australia with the fires."
Family and friends rushed to comment on the post.
A family member wrote: "Aww you both look brill. Hope you do well. Love you."
