A Gold Coast mother who went missing more than a decade ago likely suffered a violent death at the hands of her bikie boyfriend, a coroner has found.
Tina Louise Greer left home to visit Lesley "Grumpy" Sharman on his Gold Coast hinterland property in January 2012 after telling others the relationship was over, an inquest heard.
The 32-year-old Ms Greer - who had left her daughter with a friend - never returned.
Her body has never been found.
Findings of the inquest into her disappearance and suspected death were handed down by Coroner Kerrie O'Callaghan on Thursday.
Ms O'Callaghan said there was sufficient evidence that Ms Greer was dead and that Sharman was responsible on or about January 18, 2012.
Days after she left home, Ms Greer's car was found at the Governors Chair lookout at Spicers Gap - a dead end road passing Sharman's house.
Sharman, 60, was a person of interest in the case but was never arrested and died in a car crash in late 2018.
"There is insufficient evidence for me to make findings about where and how Tina died, however it is likely that she did suffer a violent death," Ms O'Callaghan said on Thursday.
"Tina Greer had been the victim of domestic violence at the hand of Les Sharman and he ultimately took her life."
Ms O'Callaghan found that the police investigations into Ms Greer's disappearance were adequate.
A lack of evidence into Ms Greer's death was due to Sharman's ability to conceal evidence and conduct criminal activity in an undetected way, she said.
In the days after Ms Greer went missing Sharman uncharacteristically switched off his mobile phone and made denials to police about the nature of their relationship, the inquest heard.
Evidence also included the history of severe physical violence and control Sharman perpetrated against Ms Greer, who moved away from him into her own accommodation.
The inquest focused on three incidents in 2010 when police at Boonah station responded to allegations of domestic violence levelled against Sharman.
The coroner found responses by a sergeant and a senior constable were inadequate but stopped short of recommending officers at Boonah police station undertake domestic violence training.
Queensland Police have since made appropriate domestic violence investigation improvements with more regarding training set to be rolled out, the coroner said.
Ms O'Callaghan recommended the police operating procedures manual be updated to provide a liaison officer for families during a high-risk missing persons investigation.
She also found the response by the Salvation Army Gold Coast was inadequate to Ms Greer's disclosures of domestic violence.
The coroner said she hoped the recommendations helped prevent deaths occurring in similar circumstances to Ms Greer in the future.
