NSW Government offer $100K reward in decade-old cold case

The NSW Government has today announced a $100,000 reward for information relating to the suspected murder of a young Sydney woman, whose body was found floating in the Sydney Harbour 10 years ago.

Katrina Ploy was last seen leaving her parent’s home at Seven Hills around 5.00pm on Sunday 17 December 2006.

Just a day later, her clothes and personal belongings were located at The Gap, Watsons Bay, and her vehicle, a dark blue 1998-model Hyundai Excel sedan, was also located nearby.


On Christmas Day, 2006, the 25-year-old’s body was found in Sydney Harbour, near Lady Bay Beach.

An investigation into Ms Ploy’s suspected murder has been ongoing ever since, however despite extensive investigations, no one has been arrested or charged in relation to her death.

Following information received from the public, Strike Force detectives have followed a number of lines on inquiry, which revealed Ms Ploy had frequented the Watsons Bay area in the weeks before her death.

Detective Superintendent Mick Willing, said witness accounts place Ms Ploy in Watsons Bay on at least four occasions in late November and early December.

“Strike Force detectives have spoken with a number of witnesses who believe they saw Ms Ploy in the vicinity of Clovelly Road and Robertson Park during this time,” Det Supt Willing said.

“The mystery remains as to why she was in the area and who she may have been visiting.

“We believe there are people who know what happened to Katrina, but have not been forthcoming with information.

Police also said investigations revealed she may have visited a tattoo parlour on the Great Western Highway, Wentworthville, in the early evening on the night she disappeared.

Ms Ploy’s sister, Tanja, said the pain of not knowing what happened to Katrina has devastated the family.

“It has been ten years since losing Katrina, but it feels like it was only yesterday that we spent the day together at the races,” Tanja said.

“Her death came as an absolute shock and there still are so many unanswered questions.

“Someone has those answers – and whoever you are – please come forward and tell the police what you know,” Tanja said.
