At the time of her disappearance, 32-year-old Ms Greer left behind her 13-year-old daughter Lili.
On Monday, detectives named Les Sharman – who was considered a person of interest in the original investigation but died in a car crash in late 2018 – as the person believed to have murdered Ms Greer.
Detective Inspector Damien Hansen said Mr Sharman was “a feared man” but following his death and a fresh appeal in January this year, several new pieces of information were supplied to police.
Inspector Hansen said police, forensic officers, SES personnel and cadaver dogs were searching 128 Aylesham Drive in Bonogin on Monday.
“We’re looking for Tina’s remains and we’re looking for evidence of the murder that has been disposed of here,” he said.
“We will be naming Les Sharman as our person of interest and that we believe he has murdered Tina.
“I’m confident we know what happened [to Ms Greer] and that will form part of our report to the coroner.
“We believe that Mr Sharman has been assisted by persons in the disposal of Tina’s body and the disposal of evidence linked to the murder.
“I’m very hopeful we will locate it [Ms Greer’s remains at the Bonogin property] and I’m very confident we will be able to prosecute further people for this offence.”
Homicide detectives do not believe Ms Greer was killed at the Bonogin property, but have turned their attention to people who might have helped dump her body.
Police stressed the current owners of the Bonogin property are not persons of interest in the investigation or under any suspicion.
Inspector Hansen said detectives had spoken to Ms Greer’s father and daughter at the weekend and they were “very hopeful we will be able to resolve this”.
Lili Greer fronted the media in January as part of the new police appeal for information, one day before the eighth anniversary of her mother’s disappearance.
“The last time I saw my mum, Tina Louise Greer, I was 13 years old,” she said.
“We went school shopping because I was starting grade 8 with my friends and we had plans to go for her birthday, which is on Australia Day, to the Currumbin Rock Pools and she was just supposed to pick me up the next day.
“Words cannot describe how much I love my mother.
“Not a day passes I do not think of her.
“I miss her more than ever.
“I am haunted daily by the unknown.”
