Anna had never had a boyfriend when she joined the cast of The Bachelor for its first season.
A 26-year-old criminal lawyer at the time, Anna has said she almost backed out of the show when she saw the other women vying for Tim’s heart.
“Mum dropped me off – and I rang her and was like, ‘oh my god Mum, I can’t do this, they’re all models, I’m so out of my league,” she revealed.
However, she went on to dazzle Tim on the red carpet and landed the very first single date.
Anna would make it all the way to the finale, where Tim chose her over runner-up Rochelle Emmanuel-Smith.
While Anna returned to her law career, she was open about taking time to adjust to the relationship in the real world.
“It took probably a good year or so. I was still wary of the fact that we were in the limelight and people wanted us to be together, so we had to separate that from our real relationship,” she said.
However, the two remained an established couple, getting engaged and then becoming the first couple from Australia’s Bachelor franchise to tie the knot in 2018.
Tim proposed to Anna during a trip to Western Australia while the pair were on a dinghy at Chamberlain Gorge.
They married in Puglia, Italy, in a stunning ceremony and followed it up with an iconic pool party for their guests the following day.
The pair now live the influencer lifestyle in Sydney and announced the news of Anna's pregnancy from lockdown in May 2020.
A month later, Tim and Anna shared the results of their gender reveal party, with a series of photos of themselves being showered with pink confetti.
They brought Elle home as a family of three in November 2020.
Anna was candid about certain issues surrounding the birth, as Elle’s umbilical cord became wrapped around her neck during the birth.
“I think going into delivery you can definitely have a birth plan, but you’ve also got to be open to things going wrong or not going the way you expected,” she told WHO in 2021.
“And I think that’s kind of the thing I’ve learned with being pregnant and becoming a mother is you’ve got to be open to letting go. You’re not going to know all the answers and sometimes you’ve just got to go with the flow.”
However, the adjustment was tough for Anna.
“There are definitely days where I’ve cried because I’ve just been exhausted, or I’ve sat down in the shower and I just want to sleep,” she admitted.
“Your emotions are all up and down, it’s like a roller-coaster. But from that moment, I just let go of everything I knew and tried to live more in the present. And I guess understanding that this is my world now, this is my new life and it’s just trying to work out how it’s all going to work.”
The couple have addressed if there’s any siblings on the horizon for Baby Elle.
“We have always wanted more than one,” Anna told WHO.
“I’ve grown up with two sisters, Tim’s got a brother and a sister, and I’ve always loved having siblings. So, hopefully one day in the future we can give Elle a brother or a sister.”
Anna, who will star on SAS Australia this year, has already been shown talking about her love for her daughter on the show.
"The one thing I want to give my daughter - if I tell her that she can do something, I want to believe it in myself," she is seen admitting tearily.
SAS Australia will premiere in February, 2022 on Channel Seven.
