"Episode 523" is the 523rd episode of the Australian soap opera Neighbours. It premiered on Network Ten on 1 July 1987. The episode was written by Ray Harding, directed by Rod Hardy, and executively produced by the serial's creator Reg Watson. "Episode 523" focuses on the wedding of popular couple Scott Robinson and Charlene Mitchell. The storyline was devised by the producers after some viewers became outraged by the idea of an unwed couple moving in together. They also believed that the wedding would be "the perfect climax" to the character's long-running relationship and an instant ratings hit.

The episode was filmed in secrecy and with a limited budget three months before it was broadcast. The wedding ceremony was filmed in the nave of The Holy Trinity Church in Doncaster. "Episode 523" is one of only a few Neighbours episodes to include the entire cast. A new romantic style wedding dress made from ivory silk, organza and chantilly lace was made for Minogue's character. The ballad "Suddenly", which was written and sung by Angry Anderson, was chosen as the theme to the episode. Prior to its broadcast, Minogue and Donovan promoted "Episode 523" by making several appearances at shopping centres.
