A baby girl found on a Queensland beach actually died across the border in New South Wales, police say.

Police divers were conducting searches at Tweed Heads on Tuesday, after the nine-month-old’s body was found on the beach at Surfers Paradise early on Monday.

It is understood postmortem results show the little girl drowned and may have been placed in the water at Tweed Heads, with her body eventually washing up 30km north at Surfers Paradise.

The baby’s 47-year-old father is being extradited from Queensland by NSW police on Wednesday. He will be charged on his return to NSW. Her 23-year-old mother remains in custody but has not been charged.

It comes as another baby girl, a four-month-old, died in a Brisbane hospital, with her death deemed suspicious.

The baby died in the Queensland Children’s hospital on Tuesday afternoon after being admitted to Logan hospital on Monday morning with life-threatening injuries.

A woman, 35, and a man, 37, are assisting police with their inquiries, with detectives from the Logan Child Protection and Investigation Unit as well as homicide detectives investigating the baby’s death.
