The images, which featured the star’s family members, also showed the couple enjoying a celebratory dinner inside the Opera House after the ceremony.
Agruma reacted to the images by leaving three red loveheart emojis on Wilson’s post.
The actress’ Pitch Perfect co-star, Elizabeth Banks, was among the first of her famous friends to congratulate the couple.
“Wow gorgeous!” Banks wrote, while veteran Aussie actress Leah Purcell commented, “Congratulations to you both!!! How beautiful to be able to share with ya Gran!!! Special! All the best for the new year!”
Former The Biggest Loser trainer Michelle Bridges also sent her love: “Beautiful! Good to have you home!” And Aussie radio star and former Bachelor runner-up Brittany Hockley commented, “How special.”
Wilson and Agruma were first married in Sardinia, Italy, in September, the location being significantly special to the pair because it was where they took their first vacation together days after going Instagram official in June 2022.
They would go on to get engaged at Disneyland in November 2022 after seven months of dating.
“We said YES!” Wilson wrote at the time alongside a series of photos taken in front of the Sleeping Beauty Castle at the famous LA theme park.
“Thank you Tiffany & Co. for the stunning ring and to Bob Iger and the incredible team at Disneyland for pulling off this magical surprise!”
That same month, the pair welcomed a baby via surrogate, a daughter they named Royce.
