Michelle Keegan will star in the new BBC drama Ten Pound Poms, created by BAFTA-award winner Danny Brocklehurst (Brassic, Ordinary Lies).
The actress, 35, will lead the original six-part series, set in Australia, alongside Games of Thrones star Faye Marsay and Luther actor Warren Brown.
The drama will follow a group who have been promised a better quality of life in Australia for only £10, leaving behind post-war Britain.
Former Coronation Street star Keegan will play young nurse Kate, who arrives in Australia without her fiancé and will do whatever it takes to "rewrite her devastating past", the BBC said.
Creator Brocklehurst said: "Ten Pounds Poms demands an ensemble cast that we are always rooting for - actors we love and want to succeed. I am thrilled to have found those actors."
"This is my third outing with the wonderful Michelle Keegan and I'm positive we will make another winner together," he added.
At the heart of the drama are Annie and Terry Roberts, played by Marsay and Brown, who are trying to do the best for their family despite the poor living conditions of the migrant hostel and local attitudes towards immigrants.
The series is currently filming in Australia.
