In the skit, Alan Fletcher, who plays Karl Kennedy, is seen calling to other Neighbours stars to come and watch the Oscars, telling them: “Get your skates on, it’s starting.”
He then says to the camera: “Darling Margot, all love to you from everyone at Neighbours.”
Jackie Woodburne, who plays his wife Susan, adds: “We’re so proud of you and everything that you’ve achieved.”
Ryan Moloney, who plays Toadie Rebecchi in the long-running soap, joked: “We’ve loved you in I, Tanya… that’s the Australian version!”
Robbie is up against Sally Hawkins, Frances McDormand, Saoirse Ronan and Meryl Streep for Best Actress at the awards.
