Happily, 95 per cent of the 35,000 Australian’s reported missing each year are located safe and well.

In NSW last year, 12,409 people were reported missing, and 84 of these have not been located.

Among these are several high profile cases from the South Coast, and despite plenty of publicity, and families who never give up searching, the cases remain mysteries.

The Rooney family of Ulladulla is approaching the third anniversary since son and brother, Owen, went missing in Canada.

He was last seen at a hospital in Grand Forks, British Columbia, on August 14, 2010.

It’s believed he attended the hospital after suffering a head injury at a music festival.

Family members spent eight months in Canada searching for Owen, supported by the Ulladulla community, at a huge financial and emotional cost.

While now back home, they refuse to give up, and are planning a media and social media blitz to mark the anniversary.

His parents spoke on Channel Ten’s The Project on Monday night, with mother Sharron saying the experience was one that “shakes you to your core”.

“I trust there will be some resolution that will come to us,” she said.

“I trust in Owen’s ability to be able to come home if he can. I trust in my own ability to find him.”

Owen’s sister Kelly told the program it was highly unusual for Owen to not contact his friends and family.

“Our family is really, really so close for him to not contact us in the early days and especially now three years later, that means something pretty heavy’s going on,” Kelly said.

While critical that a more comprehensive search wasn’t started earlier by Canadian authorities, Owen’s father Steve, is determined to continue looking for answers, and it’s clear that giving up hope is not an option.

“You’ve just got to play it as it comes. You don’t give up.”

Another baffling case is that of Eden woman Sylvia Pajuczok, who disappeared on Christmas Eve in 2008.

The 53-year-old grandmother, who was also known as Sylvia Taylor, had been staying with her brother near Rockton, south of Bombala at the time of her disappearance. 

Her Toyota Tarago was found on the Monaro Highway, locked, but with personal belongings inside including her phone and reading glasses. 

Her children said she liked to stay in contact with her loved ones especially at Christmas time.

Police believe Ms Pajuczok was murdered but her body was not been found despite a major air and ground search in the weeks that followed.

National Missing Persons Week, in its 25th year, continues until Saturday.
