'Happy birthday to my dad the greatest man I know! My hero, my mentor, my inspiration. Love ya dad,' Chris wrote in the captions.
The reel of happy memories began with a joyous video showing Chris, his mother Leonie, and brothers Liam and Luke celebrating Craig's birthday.
They all huddled around a table in the middle of a restaurant, jumping with joy and singing happy birthday around a cake topped with sparklers.
It was followed up with a photo of Chris, Liam, Leonie, 63, and Craig with their arms around each other, before the Thor star took a selfie in a Mykonos party hat.
Later in the album, the Aussie actor showed where his good looks came from with a candid of his attractive parents leaning against each other with huge grins.
