Every album she's put out has gone Gold, Platinum or Multi-Platinum. She's won 15 ARIA Awards; made it into the ARIA Hall of Fame, and sang The Flame at the Opening Ceremony of the Sydney 2000 Olympic Games — the highest-rated TV telecast in Australian history.
But Italian-born Arena is more than just a beautiful voice and an Aussie icon. In fact, her story is a dazzling mix of warmth and tragedy.
In 1995, the singer-songwriter married her then-manager Ralph Carr. And right from the words 'I do', things were never quite right.
In her autobiography, Now I Can Dance, Arena wrote that her family encouraged her to be a "runaway bride" on her wedding day. This was after she'd a disagreement with her husband, who wasn't happy at her refusal to sell their wedding photos to a magazine.
Listen: Tina Arena speaks with Mia Freedman about the debacle that was her first marriage, and why she's in no rush to wed her new partner, on No Filter. Post continues after audio.
They split up after just two years, Arena told Mia Freedman, despite the fact that their divorce wasn't finalised until 1999.
"My first experience [with marriage] was disgraceful," Arena said. "And poorly treated under Australian law, because of what I went through financially... I went back to zero after 25 years of work... I found myself getting lost. I had a very ugly divorce."
And ugly it was. Arena said she was "humiliated" and "bullied" during that time, saying the whole experience was "deeply disturbing".
