18 year old Gabriella Darlington from Pleshey in Essex has won a competition offering a part in the Australian soap Neighbours.
Gabriella will guest star as Poppy Rogers in the long-running show after winning Five's Be A Star On Neighbours contest.
The Essex student, with no previous acting experience, will start filming her four-week stint on Monday. Gabriella beat off competition from 1600 applicants and her fellow finalist for the role, Jenny Hall, who was older and had more acting experience.
"I can't believe how lucky I am. I never expected to be shortlisted, let alone get to Australia and win," she said.
Producer Neal Kingston said casting decisions were made because Darlington "ticked all the of the boxes".
She beat 1,600 hopefuls to the prize, and has spent the last week in Melbourne with the cast and crew, visiting the set and being screen tested.
"I have had an amazing week and am really excited to start on Monday," she said.
The episodes will appear on UK screens from 10 November.
A special programme documenting her visit to the set with her fellow finalist, Jenny Hall, will be broadcast the same week.
