Her defense lawyers had said that Exposto, a 54-year-old mother of four from Sydney and also a grandmother, was the victim of an internet romance scam.
Exposto has said that she went to Shanghai to meet a U.S. serviceman with whom she had an online romance and had been asked to carry a bag full of clothes. She said she was unaware that the bag also contained drugs.
Exposto had arrived from Shanghai and was to catch a connecting flight to Melbourne when she was detained in Malaysia.
Malaysia has a mandatory death sentence for anyone found guilty of carrying more than 50 grams of a prohibited drug.
Three Australians have been hanged for drug offenses in Malaysia since 1986.
