Tim, 38, and Anna, 33, announced they were expecting their first child back in May with a collage of photos of Tim and Anna posing with their ultrasound scan.
"It’s been so hard to keep this a secret, over the past few months, but I can now finally shout... I’M PREGNANT!!!" Anna wrote in her caption.
"With everything that’s going on in the world we feel incredibly lucky and grateful to be starting a family together, and we’re so looking forward to this next chapter in our lives. #BabyRobardsComingSoon"
Tim shared his own post that read: "We’ve been keeping busy in lockdown ... I can’t wait to be a Dad!!! The giddy feelings in my stomach show there must be a few nerves, but I know Anna’s going to be an absolutely amazing mother and I couldn’t be more excited to start a family with her!"
The couple later revealed that they were expecting a baby girl at a lavish gender reveal party in June where Anna admitted she and Tim were "ecstatic" to be having a daughter.
Ahead of their firstborn's arrival, the couple were living separately - Tim was in Melbourne filming Neighbours whilst Anna remained in their hometown of Sydney.
However, the former Bachelor made the decision to quit his soap acting gig to be closer to Anna especially when Melbourne went into stage four lockdown and he was unable to fly back home.
“It was a really hard decision for him to make. He wanted this role and was so happy when he got it. It’s a big thing for him to walk away from it and not see it through to the end,” Anna told Stellar.
Once Tim was back in NSW, the couple also enjoyed a getaway to Byron Bay for a luxury babymoon.
Anna captured Tim's heart on the very first season of The Bachelor Australia and professed his love for her in a romantic finale.
"It feels so good to finally be able to acknowledge what my heart is feeling," Tim confessed.
"You have my heart. I have fallen madly and deeply in love with you. Anna, I love you."
The couple then tied the knot in 2018 in a stunning wedding ceremony held in Puglia, Southern Italy and celebrated their second wedding anniversary shortly after their pregnancy announcement.
Here's to life as a family of three!
