Rhys Uhlich, a winner of Make Me a Supermodel in 2008, will appear as Scotty Boland, a love interest for newcomer Georgia Brooks (Saskia Hampele).
Scotty - described as a "country boy" - will arrive on Ramsay Street with a secret that gets people talking and changes things for Georgia, who is cousin to Toadie (Ryan Moloney).
"Ever since I got into modelling, acting has been something I've wanted to pursue," Uhlich explained to TV Tonight. "It sounds cliché, but it's a natural progression to want to move into other areas of the industry.
"I grew up in the same town as the Hemsworth boys [Philip Island], and to see the careers they've made for themselves is pretty inspiring."
Uhlich, who was a primary school teacher prior to becoming a model, began work on Neighbours last week.
He added that he was impressed by the positive reception that Scott McGregor - himself a former model - received as Mark Brennan, and joked that "some friendly competition" might tempt the Offspring star back to Ramsay Street.
His character will make his on-screen debut during December in Australia, and in February 2013 in the UK.
