A grieving mother believes crucial new evidence will finally unlock the mystery surrounding her daughter's brutal murder.

Patsy Lleiss, 87, is hopeful that a new lead will help police catch the attacker who has still not faced justice for the 1984 killing.

Patsy's daughter Lesley Patricia Larkin, 31, was found naked and covered in blood at her apartment in Noosa Heads 34 years ago.

Until now police have struggled to make progress on the case but officers now know that Lesley was frightened and experienced distressing incidents in the run up to her death.

For the first time, Ms Lleiss feels she as though she will at last find out the truth about Lesley's death.

'It's the first time I've felt really positive there might be some outcome and understanding about what happened and how it happened,' she said.

'I really feel as though something is going to break open.'

Larkin moved to Noosa Heads, on Queensland's Sunshine Coast, in an attempt to re-establish herself.

She found work as a waitress and was a regular beach goer.

On November 9, 1984, a neighbour found Larkin inside her unit, naked and lying in a pool of blood on her bed.

She had been bludgeoned several times in the head and died the next day in the Royal Brisbane Hospital.

Her mother has asked anyone who knew Lesley to cast their minds back to any unusual conversations in the lead up to her death.

'Just try to remember anything Lesley said that you might have just thought was a bit odd,' Ms Lleiss told the Courier Mail.

'I would just urge people, if there is anything to come forward.'

A State Government reward of $250,000 remains on offer for information leading to the apprehension and conviction of those responsible for Larkin's murder.

Detective Inspector Dave Drinnen said this new lead had helped to ramp up the investigation.
