Police and a rehabilitation facility had opportunities to support a woman who feared for her safety at the hands of her bikie boyfriend but did not take action, a coroner has been told.
Tina Greer went to visit Lesley "Grumpy" Sharman on his Gold Coast hinterland property in January 2012 after telling others the relationship was over.
The then 32-year-old - who had left her daughter with a friend - never returned.
Days later Ms Greer's car was found at the Governors Chair lookout at Spicers Gap - a dead end road passing Sharman's house.
Her body has never been found.
Sharman was a person of interest in the case but was never arrested and died in a car crash in late 2018.
An inquest hearing into Ms Greer's likely death has ended after 25 witnesses testified.
There is sufficient evidence to find Ms Greer was killed by Sharman on or about January 18, 2012, the day she went missing, counsel assisting Stephanie Williams told the Coroners Court in Brisbane on Friday.
Evidence included the history of severe physical violence and control Sharman perpetrated against Ms Greer and that she had moved away from him into her own accommodation with Lili, then aged 13.
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.
Ms Williams submitted that there is insufficient evidence to find where Ms Greer died or what caused her death.
"That lack of evidence can be attributed to Les Sharman's ability to conceal evidence and or conduct criminal activity in an undetected way."
The inquest heard of police speaking to the pair after incidents of violence against Ms Greer but not providing support or referrals to services, Ms Williams said.
In June 2010 when it was reported that Sharman held a gun to Ms Greer's head police had an opportunity to investigate any firearms in his possession.
But that did not occur, even though he was a known bikie member with a history of discharging and carrying weapons, she told the coroner.
Ms Williams said an officer's explanation that a search did not occur because it was likely Sharman would have hidden any weapons is nonsensical and a failure to investigate a known criminal offence.
When Ms Greer disappeared the police response was prompt and extensive, with her immediately regarded as a high risk missing person, Ms Williams told the court.
The counsel assisting submitted Salvation Army staff at Fairhaven's Gold Coast rehabilitation centre where Ms Greer was admitted in 2011 responded inadequately to disclosures about being in an abusive relationship.
Case notes refer to her not having skills or self-confidence to break away but there is nothing to indicate she was offered domestic violence counselling or referred to services.
Regarding a staff member noting she wanted to see Ms Greer given the opportunity to realise her god-given potential, Ms Williams said Fairhaven should have done more than hope for a god-given opportunity.
The inquest revealed opportunities for meaningful change, Ms Williams said.
"Lili Greer is to be commended for her perseverance and resilience in advocating for it and in doing so, advocating for her mother and other victims of domestic and family violence."
Lili Greer and other parties involved in the inquest will make written submissions to coroner Kerrie O'Callaghan, who expects to hand down findings in December.
