Elizabeth Henry, pregnant with her seventh child, was beaten and partially burned before her body was discovered outside Brisbane in 1998.
More than 25 years later, Queensland Police have offered a $500,000 reward for information that could help solve the 30-year-old’s murder.
Her heartbroken family made an emotional plea for help on Tuesday.

“We are unwavering in our hope that justice will be served for Liz,” her sister Jennifer Schefe told reporters.
“I believe there are individuals who have crucial information that could help solve the case.
“It’s not something you can take to someone’s grave.”
Ms Henry was a sex worker who was last seen in Brisbane’s Fortitude Valley before midnight on February 11, 1998.
Hours later, her body was discovered by a jogger in a gravel reserve along the road near Samford, 16 miles away.
Mrs. Henry was four months pregnant.
Police said she was violently attacked with a blunt, heavy object and was found with serious head injuries.
The clothes Mrs Henry was wearing and the handbag she was carrying at the time have never been found.
Investigations revealed that Mrs Henry was killed at another location and taken to the gravel area before an attempt was made to burn her body.
Her parents died without answer, Detective Acting Senior Sergeant Anthony Johns said.
Mrs. Henry’s six children grew up without their mother, and she would be a grandmother of six if she were still alive.

“Her parents lost their daughter, her siblings lost their sister, and her children never had the chance to know her,” Henry’s daughter Grace said Tuesday.
‘We as children had to learn to become mothers and fathers ourselves, we had no mother to call when life was difficult… I live with the loss of her every day.’
Police said neither a weapon nor the original site where Ms. Henry was killed have ever been identified.
But Detective Johns was confident the murder would be solved and said Queensland’s cold case team had reviewed the case and uncovered further information, without revealing any details.
“We believe that with public help, regardless of the passage of time, this crime can be solved, offenders can be brought to justice and we can provide some answers to those family and friends,” he said.
