Harley Bonner follows in mum's footsteps on Neighbours Harley and Carla Bonner from Neighbours. IT'S the soap opera storyline Ramsay St didn't see coming. Harley Bonner, son of Neighbours favourite Carla Bonner, has joined hit show that made his mother famous. Carla, who plays Steph Scully, said: "It's very exciting. I'm so proud. Harley wanted to be an actor at a young age. But I said he had to finish school first. Then she made Harley do a year of acting classes. It's given him a sense of accomplishment, rather than cheating his way into the system. Harley, 21, plays Joshua Willis on the show. The good news in the Bonner home follows Carla's bid to spread a sobering message about ovarian cancer. She is the ambassador for Girls Night Out, a fundraising and awareness effort, happening at Tabcorp Park, Melton, near Melbourne, on Saturday. Carla said: "Sadly, many women discover they have ovarian cancer when it's too late. We need increased awareness, and more research funding, to fight this cruel disease.
