Zak Stolz, the two-time Australian Ninja Warrior champion, announced his engagement to his long-time partner, Georgia, in a social media post on Monday.

The 26-year-old fitness expert shared a gallery of photos showing the couple celebrating, including a close-up of Georgia flashing a diamond ring: a classic gold band set with an oval-shaped centre stone. The pair captioned the images, "Here's to forever."

Several fellow competitors and friends responded to the announcement in the post's comments. Olivia Vivian wrote, "Wooooohooo. Congratulations to you both." Troy Cullen added, "Can't wait to see the video of the proposal," and model Onella Muralidharan commented, "Omg Congratulations!! So excited for you both."

Stolz rose to prominence on Australian Ninja Warrior and won back-to-back seasons in 2021 and 2022, becoming the first competitor in the series to secure consecutive titles. In the 2022 Grand Finale, he was named the "furthest fastest" competitor after an otherwise strong run. He advanced through Stage 3 but fell on the fourth obstacle and into the water, ultimately leaving the course before Mount Midoriyama. His performance that season earned him the show's top prize of $100,000.

Competing under the nickname "Zak Attack," Stolz outperformed seasoned rivals including Ben Polson and younger contenders such as Saxon Johnstone during his title runs. He reflected at the time on the difficulty of the courses, saying the season's obstacles were "just next level" and that he was "over the moon" to come out on top against strong competition.

Australian Ninja Warrior was screened on Channel Nine from 2017 through 2022. Stolz's announcement marks a personal milestone after several years in the public eye built on his television success and athletic profile.

No further details about the engagement, including plans for a wedding, were included in the post.
