Australia's foreign minister says diplomats will soon meet with an Australian teenager detained on suspicion of drug possession during end-of-school celebrations on the resort island of Bali.

Jamie Murphy was allegedly found with a small plastic bag of white powder by security staff at nightclub in the entertainment precinct of Kuta early Tuesday. The 18-year-old was celebrating with fellow graduates from their high school in the Australian west coast city of Perth.

Foreign Minister Julie Bishop told Sky News television on Wednesday that consular staff have contacted Murphy in a Kuta police cell and will meet him within hours.

News Corp. newspapers reported he could be sentenced to 12 years in prison if the powder proves to be less than 5 grams (0.18 of an ounce) of an illicit drug.
