Margot Robbie is backing a campaign to help viewers of the show stop smoking.
The Neighbours actress, who plays Donna Freedman, and co-stars including Sam Clark (Ringo) and James Sorenson (Declan), have just finished filming a scene designed to discourage teenagers from getting addicted to the habit.
It might sound like a straightforward task, but the shoot involved some embarrassment and discomfort for Margot - in soaring temperatures and amid sniggering from the cast and crew, she was forced to wear a fancy dress costume in the shape of a giant cigarette butt.
Margot recently clocked up 12 months as a Neighbours regular, and has quickly become one of the programme's most popular faces.
She'll be in the thick of things during the next few weeks when her sassy mum Cass arrives in Erinsborough and immediately sets her sights on Paul Robinson.
