Neighbours (1985) - 6 mistakes in entire show

Plot hole: Tahnee was sent to boarding school when she got fired as a way to get her out of the show, but she was 17 and so isn't that a bit of a silly way to write her out? In Melbourne Australia, you can leave school if you wish at 15, so she in theory shouldn't be able to be forced into going to Boarding School.

Continuity: Tahnee and Nina found various copied pictures of Harold with different crazy hair styles in the trash at Lassiters. When Harold found the original images, there were many pictures of the people from Ramsay street, but only one of Harold.

Continuity: In the episode that aired in the UK on the 10th March, 2004, Harold was almost run over when he was on a walk. The Harold on the road was mostly bald and wasn't wearing glasses. Ian Smith that plays Harold has most of his hair and Harold was wearing his glasses in the next shot.

Deliberate "mistake": Nina first wrote 'Born to Try', the song which was being released by Delta Goodrem (the actress that plays her), along with the show. She then managed to just 'inprovise' the tune and words to her (Delta's) third single 'Innocent Eyes'. I'm sure now Nina is a popstar there will be many more to come.

Plot hole: In the 20th anniversary episode "Friends for Twenty Years" Libby Kennedy is shown staying in Sydney. But she's supposed Adelaide as part of her teaching job.

Continuity: Back when Nina was recieving text messages from Taj, her phone used to ring when she got a text, but sometimes it made a text alert noise. She also read one of the messages before it came on the screen (the shot was of the screen).
