The final episode of "Neighbours" will feature actors Margot Robbie, Delta Goodrem, Jesse Spencer, Kym Valentine, and Carla Bonner.

According to Network 10, Robbie's comeback to "Neighbours" will consist of a "minor cameo role.

Delta Goodrem, a recipient of an ARIA Award, will also appear once again to close the night.

Initially, Goodrem played Nina Tucker in the show from 2002 to 2003. When she played the lead song from "Innocent Eyes," "Born To Try," in an episode of the show, it helped her break into the mainstream music industry.

Billy and Libby Kennedy, who are portrayed on-screen by Jesse Spencer and Kym Valentine, respectively, will also appear in the conclusion.

The return of Carla Bonner, who debuted in 1999 as Stephane Scully, has also been announced by Network 10. She has frequently come back to the show to reprise the part.

After initially announcing that Kylie Minogue and Jason Donovan would return to continue their character arcs from the 1980s, Network 10 has been dribbling out information regarding the show's last episode.

As "Neighbours" ends its 37-year run, the return of the big-name stars as their original characters will help.
