Sydney Sweeney and Scooter Braun are in a state of euphoria … all grins while walking across a tarmac and jumping in a private jet together.

Photogs captured the pair in Queensland, Australia on Friday … Scooter is seen pushing along the luggage while a smiling Sydney grasps his right hand.

Sweeney boarded the PJ first … followed closely by Scooter. Unclear where they’re jetting off to … but one thing’s for sure … they’re gonna look adorbs together no matter where they are.

We’ve seen them everywhere from knockin’ boots, so to speak, at Stagecoach to singin’ Neil Diamond at karaoke … and they’re always serving couple goals to the max.

Sweeney’s reportedly shooting a new project down in the country … the movie “Gundam,” based on the mecha anime series “Mobile Suit Gundam.”

We’ve spotted Sydney a few times in Australia in recent weeks … including a high-flying moment where she took a tour of one of Sydney’s most famous bridges. Scooter didn’t join her on that particular excursion — nor was he with her when she fed a giraffe.
