But the Tonga-born girl vanished in Canberra on December 17, 1992 at the age of 17, after leaving a relative’s home to go for a walk.

Family and friends are holding their third “Hope for Amelia” golf day in Dubbo this Sunday to celebrate Amelia’s birthday and remember her.

“It’s a day where you just enjoy yourself and go around the golf course,” Amelia’s father John Hausia said.

“It’s good to get together.”

The last time Mr Hausia and his wife MaryAnn went to the missing persons unit, they told other families of missing people that they held a “hope day” every year.

“Everyone thought it was a really good idea,” Mr Hausia said.

“Some of the families said they might even come to Dubbo for Amelia’s hope day this year.”

Mr Hausia and his wife MaryAnn live in Dubbo and have not seen Amelia for 19 years now.

The Australian Federal Police missing persons unit unveiled a billboard-sized age-enhanced photograph of Amelia at Sydney’s Kingsford Smith Airport earlier this year, giving Mr and Mrs Hausia hope.

The couple is travelling to Melbourne in early August during Missing Persons Week.

Mr Hausia said they would never stop waiting to see their daughter again.

“It’s got worse over the years. We live in a constant state of stress and agony.

“Each time the phone rings we think it could be Amelia.

“We study faces on television and in the street hoping to see our girl.

“Sometimes we catch a glimpse of familiar-looking women and chase them down.

“The not knowing drives us crazy.

“Amelia would never be so heartless to leave us dangling in this way. Something happened. We need to know.”

Mr Hausia said one of Amelia’s school friends named their baby Amelia a couple of years ago and a friend of Mrs Hausia named her baby Amelia last month.

“They said they hoped I didn’t mind, but I love the name Amelia,” Mr Hausia said.

The hopeful father said he and his family were “staying strong”.

“We hope to see Amelia again,” he said.

“We all sit back and wait and hope.”
