A four-year-old boy taken from a Brisbane hospital on Thursday by his parents, sparking a police alert, has been found with his father in New South Wales.
Queensland police said the boy and his father were found in Newcastle late on Friday and the child was taken by ambulance to John Hunter Hospital for observation.
The boy's mother had been found in the same area less than an hour earlier, having been spotted by a member of the public.
The mother told officers the father and boy were nearby when she was found, before calling her partner who brought the boy to police.
Detective Acting Inspector Grant Ralston said charges would not be likely to be laid early on Friday evening, but police would review the case into the night.
He said the situation "could have gone bad" but he was "very encouraged" by the success and scale of the police-issued Amber Alert, which included flashing signs on freeways telling motorists to look out for the family.

The parents who took their four-year-old boy from a Brisbane hospital have posted online that they believe the food and vaccines he was given put his life at risk.
Police issued an Amber Alert for the boy, named Chase, who suffers from a disability, after he was taken from the Lady Cilento Children's Hospital about 12.30pm on Thursday afternoon.
Serious concerns were held for the boy's wellbeing because his medical condition meant he was unable to walk unassisted and required urgent medical attention.
On Friday afternoon, a member of the public contacted police to say she had seen Chase and his mother, Cini Walker.
A short time later police found Ms Walker in Newcastle, northern New South Wales, but not the boy.
Acting Inspector Ralston said the boy and his father, Marc Alexander Steven, were believed to be travelling in a Honda CRV authorities had been searching for, in the northern New South Wales area.
The day before the four-year-old's disappearance, Ms Walker posted on Facebook that she and her partner had stopped vaccinating their son at age two because they believed it gave him seizures.
She also alleged it caused him to develop "spastic, quadriplegic cerebral palsy and undiagnosed, uncontrolled epilepsy".
Ms Walker also shared a video from January 18 during which she questioned whether she even owned her son any more.
"How much more do we have to prove that we love our kid?" she said.
"He needs to get better and they're destroying that."
Ms Walker said the boy did not need or want to be back in hospital. She believed the medication would harm her son and hospital food would kill him because of his dairy allergy.
"I hate watching my son being drugged up and he doesn't wake up because he's in a coma because of the medications they give him," she said.
"I've also told the doctors and the child services that I will not feed my son any of their stuff and I will fight for him not to have it.
"That will be the last thing he has because I believe he's allergic to it and he will seizure and he'll seizure to the point he'll die."
Police were urging anyone with information regarding the boy's disappearance to call 13 15 64 or triple-zero.
