Sarah Jane Holland-Batt told the hearing in Brisbane that a whistleblower informed the family her father was being deliberately victimised by a carer after a tennis ball-sized infection was noticed on his elbow in March 2017.

"I was incensed, absolutely incensed," Ms Holland-Batt told the hearing.

"The whistleblower relayed to mum that dad had been deliberately left in distress in unclean incontinence pads for long periods, that [the carer] verbally abused him and told him that she was 'sick of his shit', [and] that she left his wheelchair away from the bed so he was left completely immobile and just stuck in bed," Ms Holland-Batt said.

"[The carer] shut the door on him and told other staffers he was sleeping when he was awake and needed toileting and showering."

The carer also allegedly failed to notice the large infection on his elbow when showering him.

Ms Holland-Batt met with the facility manager — who attended the meeting dressed in a "St Patrick's Day mardi gras necklace" — and was told the staff member would be moved to another wing, and the matter investigated internally.

Her father had also been prescribed nausea medication by a GP at the nursing home, which effectively negated his Parkinson's disease medication.

It was only months later after being admitted to hospital that the medication problem was noticed.

The commission heard her father was often found by family members looking dishevelled, in unclean clothes and with small injuries including grazes, infections and cold sores.

Carer 'sadistically and deliberately abused dad'

Ms Holland-Batt tried lodging a complaint with the Aged Care Complaints Commission (ACCC).

"I was worried that this person, who had quite sadistically and deliberately abused dad, was still in the same position," Ms Holland-Batt said.

She said she was frustrated by a series of interactions with the ACCC which said it could not do anything about the staff member.

In another call the ACCC said it was still unable to substantiate the allegation, despite the whistleblower coming forward.

"They were going to do … it was just a bunch of jargon — it was things like, 'We are going to do toolbox sessions, we'll add it to the staff meeting' — to me, nothing substantive, but the laundry list of relatively low-level things they were going to do," she said.

She said the facility eventually told her they had substantiated the allegations and that the carer "no longer worked at the facility, effective immediately" but would not say in writing that the allegations had been substantiated.

A week later the ACCC called her again.

"The complaints officer relayed to me further measures that the facility was going to take and essentially said to me: 'This is about as far as we can get with this. This is about as much as we are empowered to ask them to do'," Ms Holland-Batt told the hearing.

Ms Holland-Batt said she felt the complaints process had done nothing to resolve the issue and she never felt the regulator was on her side.

"I was better off trying to pursue it myself by encouraging, with mum, the whistleblower to come forward and substantiating it myself," she said.

Commissioner Richard Tracey told Ms Holland-Batt her evidence had been extremely helpful.
