The 69-year-old actress and The Deadpool and Wolverine star, 56, and wed in 1996 and have two adopted childrens – Oscar Maximilian Jackman, 24, and Ava Eliot Jackman, 19 – but they shocked fans when they announced their separation in September 2023 after 27 years of marriage.
Jackman has since moved on with 49-year-old theatre star Sutton Foster – who he worked with on the 2022 Broadway production The Music Man – and Furness says she is focused on herself and is exploring new career opportunities in her native Australia and New York.
Speaking to the Herald Sun, she said: "I've had a few offers for films back (in Australia) so I'm still reading some scripts so if there's something that's great.
"I've got some projects in New York. I'm in my chapter three. I'm a creative, I love being creative in a variety of areas and I think I'll be doing more travelling."
She then divulged: "I'll be taking more time for myself."
This is the first time Furness has spoken since her former spouse stepped out for dinner in Santa Monica with Sutton on January 6, with the pair arriving together holding hands.
Two days earlier, Jackman was seen in the audience of one of Sutton's final performances of Once Upon A Mattress at Los Angeles' Ahmanson Theatre.
The award-winning actress previously hailed the Marvel star one of her "best friends".
Announcing their split in a joint statement, Jackman and Furness told People magazine: "We have been blessed to share almost three decades together as husband and wife in a wonderful, loving marriage.
"Our journey now is shifting and we have decided to separate to pursue our individual growth.
"Our family has been and always will be our highest priority. We undertake this next chapter with gratitude, love, and kindness.
"We greatly appreciate your understanding in respecting our privacy as our family navigates this transition in all of our lives."
They signed off as "Deb and Hugh Jackman" and concluded: "This is the sole statement either of us will make."
