Sheila receives a warm welcome from Kyle (Christopher Milligan) as she arrives on Ramsay Street, and soon enjoys meeting some of the locals as the handyman takes her on a tour of Erinsborough.
When Sheila bumps into Kate Ramsay, she wrongly assumes that she is speaking to Kyle's girlfriend Jade and is thrilled - impressed by Kate's good manners and cheerful demeanour.
It's unwelcome news for Sheila when she hears that Kate is just a friend of Kyle's, and when she is finally introduced to Jade at Number 26 later in the day, she is far from pleased!
Jade (Gemma Pranita) thinks that she has managed to make a good impression on Sheila, but in private, Sheila tells Kyle that he is with the wrong girl. How will Kyle react, and can Jade win Sheila over?
Neighbours bosses announced the casting of former Prisoner star Colette Mann as Sheila earlier this year.
Sheila is a new regular character for the soap, and Mann has said that she is enjoying injecting some "wicked humour" into the street.
Neighbours airs Sheila's first scenes on Thursday, May 31 at 1.45pm and 5.30pm on Channel 5.
