Some western Queensland students have been unable to attend their first days of boarding school due to the floods.
Morven mother Marie Williams says they are waiting until at least Friday to begin the seven-hour drive to Toowoomba Grammar School.
She says her son will miss orientation and the first few days of schooling.
"We're getting constant emails from the school just to keep in contact with us," she said.
"They're telling us not to be too concerned, staff at the school are structuring classes accordingly.
"We can only try to get there when we can and they're very understanding, I think, the staff at the school."
Toowoomba Grammar School headmaster Peter Hauser says as of yesterday, one-third of their boarding students had not arrived.
He says Toowoomba has many boarding schools in the area all in a similar situations.
"Toowoomba is a major hub for boarding schools - we've got 11 in the Darling Downs and Toowoomba district and we're getting boys and girls from all over Australia," he said.
"So look, everybody's facing the same, there will be delays.
"I know one of the schools ... delayed the commencement of the school year by a day, so no everybody's experiencing the same."
