"Being married to you Deb is as natural as breathing," Hugh adorably captioned the carousel. "From nearly the moment we met ... I knew our destiny was to be together. In our 25 years - our love has only grown deeper. The fun, excitement and adventure more exhilarating; the learning even greater."
He continued, "I'm forever grateful to share our love, our life - and, our family together. We've only just begun. Deb, I love you with all my heart!"
Several of the pics show the couple with wide smiles on the special day, while another shot features them enjoying a kiss and tender embrace.
The pair, who share two children together, met on the set of the Australian TV series Correlli in 1995 before tying the knot the following year. Correlli starred Deborra-Lee as a prison psychologist and provided Hugh with one of his earliest roles.
During a September 2020 interview on Anh's Brush With Fame, Deborra-Lee reminisced about the couple's "amazing" initial connection.
"When you find a partner in crime that you share and you grow together—and life is tough, as we know it, it's not all good—and when you have someone there that is so supportive…you can really stand buck naked. You have to," the 65-year-old performer shared.
She added, "When you've got kids and life and whatever, you stand there buck naked, authentic, warts and all, this is who it is, and you're loved, there's nothing better."
