Michelle Keegan stuns in a vintage tea dress as she shares BTS shots from filming Ten Pound Poms

Michelle Keegan shared a series of behind-the-scenes shots from filming her new drama on Sunday ahead of its release next week.

The 35-year-old actress plays nurse Kate Thorne in the upcoming BBC show about the famous Assisted Passage Migration Scheme, which brought more than a million people to Australia after World War II.

Michelle took to Instagram to post the slideshow of images and looked stunning as she posed in a vintage purple tea dress all at once.

Another photo showed the star and cast members grinning in 1950s finery as they relax on set.

Elsewhere in the gallery were snaps of the scenery for the BBC show, a beautiful sunset and an image of Luna Park, a theme park in Melbourne.

She captioned her post: “1 week left before Ten Pound Poms takes you back to 1956.”

It comes after Michelle opened up about the daunting task of spending months away from home and husband Mark Wright, 36, while filming the new series.

The actress, who married the reality star in 2015, described traveling alone as “pretty scary” as she left her life and loved ones behind in the UK as filming took place last summer.

Reflecting on the production process, she said: ‘I absolutely loved filming in Australia. I mean when I first got there the weather wasn’t great I’m not going to lie but as a country I really enjoyed it.

“In a way, my trip to Australia parallels Kate’s. It was also my first time and I didn’t know what to expect. I came alone, which was kind of scary, but it was such an incredible experience.”

Mark did manage to take trips to visit his wife down under and the pair shared snaps of their romantic reunions on social media last year.

Discussing their “difficult” long-distance relationship in July, Mark told MailOnline, “If you’re in love and in a happy relationship, you’ll be happy to see each other.”

“You have to learn that you’ve been together for a long time and haven’t seen each other for three weeks, so it’s exciting at first, but then it becomes another ten-year relationship.

“The longer you go, the more pressure there is, because the longer it’s been. But I was in LA having dinner with Piers Morgan and I told him it was hard. He said, ‘I had this with my wife and we have a 3 week rule so don’t let it go past 3 weeks.’

Before continuing, say, “It’s hard with Australia though, it’s a lot of flying.”

Michelle also discussed what she loved about the country ahead of the show’s upcoming premiere.

Gushing: ‘The Australian actors are so brilliant and they bring a different energy to the set’.

“What I miss most about Australia is the people. I know it’s such a cliche thing to say, but everyone is so nice, friendly and welcoming. The crew really got along and it was such a great work environment – and of course I miss the cast.”

Discussing the show’s difficult topic, she said, “Ten Pound Poms will definitely take the audience on a journey.”

“I think the script is like a history lesson for me and for the viewers. I didn’t know much about the Ten Pound Poms before I was part of this project, but I’ve done a lot of research on them.”

Before I add: Now I’ve talked to a lot of people who say, ‘Yes, my grandmother was a Ten Pound Pom and I have relatives in Australia’ and that all stemmed from what happened in the 1950s.

Earlier this week, the show’s trailer debuted, featuring actors Faye Marsay (Game of Thrones) and Warren Brown (Luther).

They play a married couple, The Roberts, who come to Australia in 1956 after paying just £10 for their departure.

The Australian government promises them a better home, better job prospects and a better quality of life Down Under, far away from gloomy post-war England.

But soon the family discovers the grim reality of migrant life as they struggle the poor living conditions in a hostel for ‘New Australians’, but also prejudices.

The series will premiere on BBC1 on Sunday 14 May at 9pm
