The Australian Federal Police (AFP) is seeking the public's help to find three children abducted by their father in Queensland a year ago.
It comes after the Federal Circuit Court of Australia issued a recovery order for 13-year-old Jessica, 12-year-old Levi and 11-year-old Blake Moore who are likely to be with their father, 40-year-old Tobias James Moore.
The court also allowed photographs and details of the children and their father to be published in the hope someone will come forward with information on their whereabouts.
The AFP said Mr Moore abducted his children in September 2017 and was last known to be living around Proserpine in north Queensland in May this year.
The family previously lived in the Logan and Redland Bay regions, near Brisbane.
The court order authorises the AFP and state and territory police to recover the children and return them to their mother.
Jessica is described as having long blonde/brown hair, hazel eyes and fair skin, while her brother Levi has brown hair, brown eyes and fair skin.
Blake has short blond hair, blue/green eyes and fair skin.
Mr Moore is 40 years old, with black hair, brown eyes, fair complexion, about 173 centimetres tall and slightly built.
The children's mother has declined to comment.
The case comes after other recent Queensland cases of parental abduction.
Police said anyone who helped an abducting parent could be committing a crime.
Anyone with information on the Moore family is urged to contact the AFP on (02) 6126 7926.
