Queensland daycare worker under investigation for allegedly mistreating a toddler

A childcare worker accused of mistreating a toddler is understood to be back working in the sector while still under investigation.

Police are probing allegations a three-year-old boy was grabbed, thrown onto a mattress and screamed at by his daycare worker in south-east Queensland.

His mother, who cannot be named for legal reasons, told 7NEWS she and her partner were left shaken after watching security footage of the alleged assault.

“Both myself and my partner were sick. And those that were around us at the time were just shaken,” she told 7NEWS.

The centre, which also cannot be named for legal reasons, has since confirmed the woman is no longer employed there.

In a statement provided to 7NEWS, the childcare provider said it has “provided the highest quality care to Queensland families for more than 17 years” and stressed “the safety of the children in our care, and the peace of mind for their families and carers, is our number one priority.”

The centre said it took immediate disciplinary action involving the now former employee in full compliance with the Department of Education, and that the matter remains under investigation.

It added it welcomes stronger child safe reforms and a proposed national register to ensure unsuitable workers are removed from the sector.

7NEWS understands the worker’s Blue Card has not been suspended and she is now employed at another childcare centre just two suburbs away.

“She shouldn’t be able to work. That Blue Card should be suspended, “ the mother said.

The new centre has not responded to a request for comment.

Child Safety Minister Amanda Camm said the government would do everything in its power to ensure systems meet community expectations.

A review of the Blue Card system is due to be handed down next month, with mandatory reporting of staff misconduct to come into effect from July next year.

Child safety advocate Hetty Johnston urged governments to “spend whatever money has to be spent” and make reform the top priority.

Parents say the system must be strengthened immediately to protect vulnerable children.

Police are investigating the incident and no charges have yet been laid.

In recent months, Queensland has grappled with serious safety incidents ranging from alleged torture and physical abuse to indecent treatment and negligence.

A convicted child rapist worked at his wife’s Beenleigh daycare without clearance, while a 21-year-old childcare worker has been charged with indecently treating a four-year-old at a Brisbane centre despite holding a valid Blue Card.
