The hit series embarks on a trip Down Under as Long Lost Family gets an Australian version, in which intrepid presenters Anh Do and Chrissie Swan travel the length and breadth of the country to try and unite family members who have been separated for decades.

This week begins with mum-of-four Emma, 36, who’s looking for her birth father Ken. All she knows is that he lived on Phillip Island, Victoria, where her parents met as teens in the summer of 1978.

In New South Wales, Sian Cavanagh, 27, is looking for the half-sister she’s never met and desperately wants to find.

But does Alana know she exists?
