Neighbours has revealed Matt Werkmeister and Kaiya Jones as the two stars set to return to Ramsay Street.
The pair, who portrayed Zeke Kinski and Sophie Ramsay, will guest in a special celebration episode due to air in April on Australian screens.
Werkmeister - who appeared as the youngest Kinski from 2005 to 2011 - will make his return as on-screen stepmother Susan Kennedy (Jackie Woodburne) and stepfather Karl (Alan Fletcher) celebrate their 20th year on the show.
"It seems like yesterday that Matt walked on set as a young boy still at primary school, and suddenly now he's a grown man," Woodburne said. "We have shared a lot of fun storylines as well as a few tragic ones, the full gamut."
Meanwhile Jones - who was last seen as Sophie in 2013 - returns to Erinsborough before on-screen sister Kate Ramsay (Ashleigh Brewer) departs.
Last week, Neighbours show chiefs left fans to guess who would return to the soap using an old cast shot.
Jane Hall recently reprised her role as Rebecca Robinson, while Australian viewers have already seen Scott McGregor make his return as Mark Brennan.
