A tourist couple had their bag snatched outside the Perth Mint on Hay Street on October 6.
Between 12.40pm and 1.10pm, the pair placed the carry bag on the ground while taking a photo outside the building.
While they were occupied, an unknown male snatched the bag and belongings.
The bag was later found discarded without its contents.
The couple came to Perth to celebrate their upcoming wedding.
They are desperate to retrieve some of the items, including a camera.
The male (pictured) is described as fair-skinned, average build, between 180 and 185cm tall, with light brown hair.
He was wearing a black T-shirt, black collar jacket, dark blue jeans and dark grey shoes.
