The doors on Ramsay Street are set to close but the surprises about the Neighbours July 28 finale are still coming.
Oscar-nominated actor Margot Robbie and a handful of international names have been confirmed to return for the final episode of the long-running Australian soap.
The show's official Twitter account revealed the news about Robbie's appearance early on Sunday morning.
Her return was announced alongside that of former stars such as singer and actor Delta Goodrem and House actor Jesse Spencer.
Robbie's character Donna Freedman appeared as a regular on Neighbours from 2008 to 2011.
The I, Tonya and Bombshell star is playing Barbie in Greta Gerwig's forthcoming film.
When her contract with Neighbours came to an end, Robbie was offered a chance to stay on.
Instead, she went on to star in the American drama series Pan Am before launching a major Hollywood career.
Earlier this month, photos of Kylie Minogue and Jason Donovan filming the show's final episode were shared on Twitter.
The Australian soap launched the international careers of Robbie, Minogue and Donovan, along with Russell Crowe and Guy Pearce.
The program first aired in 1985 and followed the lives of those living and working in the fictional Melbourne suburb of Erinsborough.
It was cancelled earlier this year after Britain's Channel 5 announced it would drop the Australian soap from its line-up.
Cast members, including Pearce, Natalie Bassingthwaighte and Alan Fletcher, paid tribute to the long-running series on social media last month, sharing moments from their last days on set.
Neighbours will officially end with a 90-minute special to be simultaneously aired on Channels 10 and 10 Peach from 7:30pm on July 28.
