Day care provider Goodstart Early Learning has suspended its bus services nationwide - including at the centres in Wagga - after the death of a toddler this week.
Goodstart CEO Julia Davison has announced an investigation into the circumstances surrounding the death of the small boy in Cairns on Tuesday.
"While we don't yet understand the circumstances of yesterday's tragedy, we will of course do everything in our power to assist the authorities with their investigation," Ms Davison said.
"Over the coming days we expect to understand more about this devastating incident."
Goodstart Early Learning operates seven centres in Wagga - in Kooringal, Ashmont, Central, Glenfield Park Lake Albert and Estella - as well having one centre in Junee.
Parents were informed that the bus services at each of the centres would be temporary suspended while a review of processes and procedures takes place.
"We have made the decision to temporarily suspend our bus services from today [Wednesday]," Ms Davison said.
"This was not an easy decision to make as this service enables many vulnerable children to access early learning, however we need to ensure our safety processes and procedures are the best they can be."
Bus services completed scheduled pick-up and drop-off on Wednesday, "with additional checks in place until all children are home this afternoon [Wednesday]."
Staff and families from the Edmonton facility in Cairns have been offered counselling and that centre will remain closed this week.
"Goodstart Early Learning sends its deepest condolences to the family of a small boy who died in our care in Cairns yesterday," Ms Davison said.
"It is a great responsibility to care for a child and each day tens of thousands of families entrust their precious children to us. It is not a responsibility we take lightly."
