A preschool where a toddler was left inside a bus for up to six hours has two signs right out the front warning parents to 'never leave children alone in a car'.
Nevaeh Austin, three, was the only child collected in the daycare bus on Wednesday morning and taken to Le Smileys Early Learning Centre at Gracemere, near Rockhampton in central Queensland.
However, the little girl never made it out of the bus.
The worker and female bus driver who were supervising the toddler seemingly forgot she was in the bus at all - leaving her to suffer inside the scorching vehicle all day.
Nevaeh is now fighting for life in hospital with kidney failure after she was found unconscious, steps away from two signs warning of the dangers of leaving children in hot cars.

'Never leave children alone in a car,' one sign reads.
'Four-and-a-half minutes inside of a car could be as high as 70 degrees.'
The warning also outlines health risks, including heat stress, dehydration, brain injury, serious kidney damage, and death.
'Always check your back seat is free of passengers before leaving your car,' the sign reads.
Nevaeh was taken to Brisbane Hospital on Wednesday night for an urgent deep brain scan and treatment on a failing kidney. Doctors say her condition is critical, but stable.
The centre's owner Michelle O'Rourke - who was not one of the two staff members on the bus - said on Thursday that she had chosen to close the centre in the wake of the tragedy.
Police said the centre was under no obligation to close.
She also vowed not to continue the shuttle service to and from the centre in the future.
'I apologise to families for the inconvenience however, Le Smileys Early Learning Centre will no longer be providing transportation in any form, from this point forward,' she said in an email sent to families.

The email was reportedly the first correspondence some parents had received from the school despite the tragedy coming to light hours earlier.
Distraught parents arrived to pick up their children on Wednesday afternoon, marvelling at how a task as mundane as the pick up and drop off could go so wrong.
One mother claimed she was never contacted about the incident and was instead left to read about it on social media.
At the time, the only details available to her online were that an unnamed three-year-old at her own child's day care was fighting for life.
Capricornia Police District Detective Inspector Darrin Shadlow said the facility and the staff members involved have now sought legal advice.

They're assisting the investigation 'to a degree' but contacted lawyers and 'will be going down that path'.
Mr Shadlow told reporters on Thursday morning that the investigation was still in its early stages, but it appears Nevaeh appears to have been the only passenger.
'It would appear she was the only child at the time,'
