"Happy birthday to my favourite person in the world. I can’t wait to stand on my tippy toes and snap my neck to kiss you for many more years to come. Love you Noosh," Olympia captioned the photo she shared to her 212,000 Instagram followers on Friday.
The glamorous couple met on exclusive dating app Raya, which only allows people with verified social media accounts and requires a recommendation from other users.
The couple then announced their engagement last October.
"Today is a special day. The man of my dreams proposed to me. I get to marry my best friend @thomas_bellchambers," Olympia captioned her post at the time.
Groom-to-be Tom shared the same photo of himself and Olympia along with the caption: "Couldn’t be happier...stuck with me now."
Olympia, a former Dancing With The Stars contestant, revealed her and Tom spent last year's Melbourne lockdown at their property just outside of the city in the Daylesford/Hepburn region.
"It’s been such a mixed bag of emotions if I’m being honest. There are days I have absolutely loved doing nothing, and really just teaching myself to slow down," she told WHO at the time.
"We’ve been doing some work around the house and on the garden, and our chickens are my new pride and joy! I never normally get this much time at home so that has definitely been a blessing."
