The actor was also joined by his younger brother Dylan Efron for the day out at the beach

Zac Efron is spending some quality time with his little sister!

On Tuesday, the actor, 36, shared a sweet Instagram video of himself playing in the sea with his 4-year-old sister Olivia, as well as his brother Dylan Efron.

At the start of the video, Zac planted kisses on Olivia’s cheek while carrying her as she looked out into the ocean.

“Ah ah, wave,” Olivia yelled before her elder brother lifted her by her hands as the waves met their feet.

Dylan, 32, then joined the duo as he and Zac swung their little sister over the water.

“First day of spring ☀️,” Zac's caption read.

Dylan also shared a video of himself and Olivia playing in the sea on his own Instagram account with the caption, "'it was a perfect day’ - Olivia."

Zac and Dylan are the proud sons of parents of David Efron and Starla Baskett, who divorced in 2016.

David then welcomed the brothers’ younger half-siblings, Olivia and Henry, during his second marriage.

Zac and Dylan often share snaps of each other, as well as their younger siblings, on social media.

In October, Dylan penned a sweet tribute to The Iron Claw star on his 36th birthday alongside a carousel of images that included a photo of all four of the siblings.

“HBD Big Bro 🎈I know exactly the type of big brother I want to be for Olivia and Henry because you were that brother to me,” Dylan wrote. “Thankful for all the memories made this year but I think we’re overdue for a real adventure, let’s do something crazy this year 🤟.”

Dylan also joined Zac at his Hollywood Walk of Fame star ceremony, where Efron opened up to PEOPLE about the sacrifices their parents made for him so he could achieve his acting dreams.

“My mom and dad, they're the reason I'm here today,” Zac told PEOPLE in December after the ceremony. “They believed in me when I don't know how they did. It must've been difficult to drive me back and forth to auditions when I was 15, three hours from the Arroyo Grande out here, just to have such a small shot.”

“They believed in me, and they stuck with me, by my side, through all of it. And I think they sacrificed a lot to support me throughout the years,” he continued. "So to have them here and to both be here in person is ... it makes me emotional, man. It's very special. It means the world to me.”
