“I said, ‘yeeeES!!!’,” Grace said in an Instagram post.
“OATH YES! Love you forever and ever angel man.”
Grace shared three photos in the announcement celebrating their milestone.
The first was of the loved-up pair as Grace showed off her new ring.
The second photo captured the moment Max asked the question.
“And to my cousin Eloise (Weasy bun) for capturing the surprise from the bushes on our ride this morning haha,” Grace said.
The final picture was a close-up of the ring, which is an unconventional sapphire ring made by Tender Scars.
Max and Grace met the week before she was named Australian of the Year in 2021.
