A two year old boy allegedly abducted from the northern Brisbane suburb of Zillmere by his mother, has been located about 800 kilometres away in New South Wales.

Police said the boy was found safe at an address in Merriwa, in the Hunter region, about 3.15pm on Monday.

Investigations into the boy’s disappearance will continue, police have confirmed.

On Sunday, the boy’s mother was reportedly seen taking the boy from the Beams Road house and then walking him to the nearby Centro Taigum Shopping Centre.
