A woman accused of kidnapping her baby daughter from the United States two decades ago will face an extradition hearing in Queensland.

Dorothy Lee Barnett, 53, is facing charges on Tuesday of international parental kidnapping and making a false statement on a passport application in the US.

After losing custody of her 10-month old daughter Savanna Todd in 1994, Barnett allegedly abducted her from South Carolina during an outing.

Police said Barnett left for a birthday party with her daughter and never returned. A US arrest warrant for Barnett was issued that year.

In November last year, Australian and US police found the pair living on Queensland’s Sunshine Coast.

Barnett has been denied bail pending extradition back to the US, where no court date has been set.

An extradition hearing will be held in the Maroochydore Magistrates Court on Tuesday.

If convicted on all charges, she faces more than 20 years in prison.

The daughter Barnett is accused of kidnapping all those years ago appeared at previous court hearings to support her mother.
