In one clip, Lara filmed herself and friend Phoebe Tonkin laughing as they posed in front of a mirror.
Phoebe, a fellow model, is currently filming Transfusion with Lara's husband, Sam Worthington.
One black and white candid photo also showed Lara and Sam's two eldest sons, Rocket, six, and Racer, four, fishing on a pier.
Lara is also mum to River, one, though he didn't appear in any of the photos.
In her final black and white snap, Lara shared one of herself celebrating with a birthday cupcake.
Lara and Sam, along with their three kids, relocated from LA to Sydney in January.
Speaking to Sunday Life earlier this month, the mum-of-three said that her boys are "loving" life Down Under.
"The juggle is a lot, but it’s good," she told the publication, adding that she's been "that routine mum" since the kids were born.

However Lara admitted there are times, like when the children are sick, when that routine goes out the window.
"Those days make it more interesting. I’m pretty level-headed, so nothing really rattles me. I get enjoyment out of organising, and making things a bit simpler for them.
"But when it comes to me personally, that’s not the case. My wardrobe is chaos; my make-up bag is a mess."
