The couple had been dating for just a month after meeting on the high-profile dating app, Raya, around the time of Olympia's grandfather, 88-year-old Dimitri Gogos' passing.
The 29-year-old described Thomas' support through the tragedy to WHO as "really amazing."
"He has come to me at a good time in my life," she adds.
The pair were instantly smitten, with Olympia going on to say that just a few months into their romance they were already living together.
"We live together; we haven't spent a night apart since. I'm absolutely happy."
Life soon began imitating art for the actress and WAG.
When chatting to TV WEEK for season two of AFL drama Playing For Keeps Olympia joked about the parallels of playing on-screen WAG Tahlia Woods and supporting AFL star, Tom, from the sidelines in real life.
"There are definitely similarities," she said with a laugh. "It's hilarious, really. Sometimes I read the scripts and I'm like, 'Is this my life?' Some of the conversations in the show are ones I've had with Thomas.
"I know far more about the game than I ever did before – and I watch the football all the time now."
Thomas confirmed to the Herald Sun that he and Olympia had purchased a "country weekender" together near Daylesford, Victoria.
"We'd love to spend 2-3 days a week up there," he told the publication.
"It's an exciting next step for us. We are both super happy and couldn't be going better."
Ever since they've been sharing loved up and scenic snaps from the gorgeous property.
They broke their engagement news on Instagram while on an idyllic vacation through Queensland, the star shared a loved up snap to celebrate that Thomas had popped the question.
"Today is a special day. The man of my dreams proposed to me. I get to marry my best friend," she wrote.
Thomas shared the same photo on his Instagram, writing: "Couldn't be happier...stuck with me now. 💍❤️"
