In the second photo, Chris also shared a snap of the core family of five with birthday boy Luke in the centre.
Whilst Luke poses with a serious expression on his face, the rest smile for the camera with their arms around one another.
The final photo is a candid shot of Luke sitting at a table in what appears to be one of the family's Byron Bay homes.
Naturally, fans couldn't help but remark how good-looking the family is.
"Dude .. their parents won the genetic lottery," one remarked.
"Why are all the Hemsworths sooooo fineeeee," lamented another.
"We love a beautiful family," stated a third.
Last month, the Hemsworths spent some time away together on Lord Howe Island east of Port Macquarie.
"2020 has been incredibly hard for communities who depend on tourism. Obviously not everyone is able to travel at the moment but once it’s safe to do so let’s support our fellow Aussies by taking a holiday at home in @Australia," Chris captioned a series of photos of himself and his family on his Instagram account.
"@visitlordhoweisland is one of the most sustainable destinations in the world with only a few hundred visitors allowed at any one time. This paradise is home to one of the most unique ecosystems in the world, but like many small communities, it relies on tourism. Thanks to @ for the hospitality."
