Jason Oppenheim and his girlfriend Marie-Lou Nurk stepped out in casual wear during their romantic getaway to the land down under on Thursday.

The Selling Sunset reality star, 45, traveled to Australia and was sightseeing in Sydney with the German model, 25, who towered over him as they stood on steps outside of their hotel.

The couple, who share a seven-inch height difference, previously traveled to Paris together and participated in a racy photoshoot.

During their outing ahead of the new year, Oppenheim sported an appropriately casual outfit for a date to tour the sights.

The president and founder of The Oppenheim Group donned a simple gray tee and gray shorts with a checker print as he waited for his ride with his girlfriend.

He wore white sneakers and carried a taupe bucket hat to wear later.

His girlfriend - who he started dating around July 2022 - donned a low-cut white bodysuit and a pair of low-rise, wide-legged pants.

She carried a small Louis Vuitton purse and wore a pair of slides. 

The newest Selling Sunset star wore a navy blue Los Angeles baseball cap and styled her hair in a ponytail braid.

While checking her phone, she showed off her various bracelets and rings adorning her hands.  

She shielded her eyes from the sun with a pair of oval-framed shades.

The couple were first linked in July 2022 - six months after Oppenheim's split from his Selling Sunset costar Chrishell Stause.

The pair reportedly started dating after meeting on vacation in Greece.

The couple were spotted sharing PDA during their trip abroad and later shared a photo posing together. 

Shortly after, they made their red carpet debut and went Instagram official. 

Although they have not been together for very long, the pair spoke with People in August about being on the same page for their future plans. 

Nurk resides in Paris where she works as a model and perhaps they will move there after filming the newest season of real estate reality show. 

Oppenheim also previously spoke about not wanting children but is now considering the next step with his girlfriend. 

'I'm more open to being a husband than I am a father right now,' he said. 'I like the idea that there's no pressure, or a thought about having to have a child with Lou. So it just makes it easy for us.'

Nurk related to the sentiment about not wanting children at the moment: 'I think for the next ten years, I'm good. And that's a long time, so I'm not even thinking about it yet.'
