In 2012, Arena and her family relocated from Paris to reside in Melbourne, Victoria. She moved back, full-time, at the end of October 2012, after almost two decades living in France and London, with her partner, Vincent Mancini and their son. Arena says, "It was time. I've been away 20-odd years, worked internationally and done some great things, I just felt it was time to come home". What Arena wants more than anything right now, is time with her family, including her parents, Giuseppe and Franca, and sisters Nancy and Silvana. ""I want to be with my family and have my son experience what it's like growing up in Australia"", she says, ""it's really important for me"".
