Daughter of woman killed in suspected murder-suicide complained of NDIS failure

Shocked friends of the woman who killed her mother in a suspected murder-suicide have revealed new details about the pair, and their lives together.

The woman believed to be at the centre of a horror suspected murder-suicide in Edwardstown claimed her mother was subject to failures at the hands of the National Disability Insurance Scheme (NDIS).

In a petition shared to change.org in September 2021 entitled “Help Trista stop abuse from NDIS”, Sally Davis appealed to readers to support her mother Trish Lambourne and “all who are suffering from NDIS abuse”.

Ms Davis said Ms Lambourne, who she referred to as Trista, had been using the scheme for more than two years.

“She has none of the help she needs, just one horror story after another,” the petition read.

Ms Davis accused the providers associated with the government scheme of a number of misconducts.

An NDIS quality and safeguards commission spokesperson said their “sympathies are with the family and friends of Ms Sally Davis and Ms Trista Lambourne”.

“As this is an ongoing police investigation we cannot comment any further.”

She claimed a local area co-ordinator (LAC) and an occupational therapist (OT) ignored the advice of Ms Lambourne’s long-term general practitioner.

The LAC “made a plan with a lot of things she can’t physically and mentally use,” Ms Davis claimed on the petition.

She also made reference to OTs using equipment that exacerbated an injury that Ms Lambourne had.

Ms Davis said she lodged at least one complaint against the workers to the NDIS.

She asked readers to share their “horror stories” in a Facebook group associated with Ms Lambourne, “so others can know that they are not alone in this.”

In an account believed to belong to Ms Lambourne, she wrote in 2021 that she and her daughter did not want the vaccine and were “ready 2 die 4 our belief (sic)”.

“My daughter takes care of me has 4 around 20 years point is I can’t handle being touched,” she wrote.

“If they take the 1 person away from me by killing her with vac then they condemn me to death also but we r ready 2 die 4 our belief.”

Meanwhile, a Kilburn couple who befriended the woman at the centre of a suspected murder-suicide say she was “completely devoted” to her mother and gave up her own freedoms to care for her.

The tragic circumstances that led Ms Davis to stab her mother in her home before setting it alight has left cleaners Alexander and Vicki Nikolic shocked and confused.

The pair met Ms Davis and Ms Lambourne more than 10 years ago while working as cleaners at the Welland Shopping Centre and appear to be among few who got to know them personally.

Speaking to The Advertiser on Tuesday, Mr Nikolic said learning their fate was like “something out of a horror movie”.

“When I saw it, I thought, what went wrong?” he said.

“Her mother had a lot of health issues, when they came in she would be fine one day and not the next. Did it all get too much for her? This is what I’m thinking.”

Ms Nikolic last had contact with Ms Davis a year ago when she saw her shopping in Blair Athol.

She said during all the years she knew her she was “totally committed” to her mother.

“She never worked as far as I knew and she didn’t have the freedom to party or mix with people. She was constantly looking after her mother.”

Ms Nikolic said she was aware of their anti-Covid vaccination status and obsession with Pokemon Go.

“They told me they weren’t going to take it (the vaccination), because it was a conspiracy,” she said.

“The daughter would also constantly be playing games on her phone.”
