A female officer conducted a frisk search and found "inconsistencies" around her bra, which turned out to be a package of white powder, customs officials said in a statement Friday.
The statement said the package contained approximately 14 ounces (400 grams) of heroin.
The 20-year-old woman will appear in court in April. She faces a maximum penalty of 25 years imprisonment and/or fine of 550,000 Australian dollars ($356,000).
