Ada – who plays Leah Patterson-Baker in Home and Away - found fame playing Katerina Ioannou in Heartbreak High back in 1994 and hardly appears to have aged a day since.
“Strutting into #strongwoman #fitness #whitebikini,” the star wrote on Instagram, alongside a snap of her in a tiny white bikini walking along a boardwalk.
Fans were quick to show their appreciation.
“Damn girl you’re sure making a mockery of ageing,” wrote one. “Beautiful.”
Ada has previously given an insight into how she stays in shape.
Taking to Instagram in October, she shared a photo of herself weightlifting in the gym.
“Weight training, fitness, squats,” she hashtagged her snap.
Earlier this year, Ada took part in an eight-week fitness challenge.
“I did allow myself a couple of cheat days,” she told WHO back in June.
“It’s been a really busy time for me, with a lot of friends’ birthdays and two engagements as well. That’s been a little challenging, not being able to drink! I didn’t really take that into account when I set out on this challenge.”
