Cabramatta Food Tour with Luke Nguyen

Luke Nguyen rips open his coat with a flourish.

Beneath his assuming attire is a fitted black t-shirt that proclaims "I love pho". It generates a round of laughter amongst the assembled crowd as he stands there, chest puffed and proud like a Vietnamese superman.

Luke's family story is not dissimilar to thousands of other Vietnamese refugees who fled to Australia following the fall of Saigon.
