Jakarta , Indonesia ( CNN ) -- A 14-year-old Australian boy accused of marijuana possession could face jail time on the resort island of Bali . With his face covered in a black mask , the teenager was mobbed by the media as he entered a local court complex for the first day of his trial Tuesday . Earlier , prosecutor Gusti Gede Putu Atmaja said the judge would not wear his usual robe to try to minimize stress on the boy . The trial is closed to the public . The Australian teen -- whose name has not been publicly released -- faces three charges under Indonesia 's stringent narcotics laws . The most serious charge of possession , under article 111 , carries a sentence of up to six years . The teen is also charged with drug use under article 127 , which could result in a maximum sentence of four years . The least serious charge , under article 128 , relates to drug use by minors and takes into account a person 's history of drug use . This charge does not hold criminal liability and could send the teen to rehabilitation instead of jail . `` We are optimistic , and we hope that we will get the result we want -- that he be returned to his parents and avoids jail time , '' said the teen 's lawyer , Mohammad Rifan . But the prosecutor stressed that article 128 stipulates a minor 's parents should report the drug use to Indonesian authorities . Any actions taken by his guardians in his home country are not recognized in Indonesia . If the teen does face a jail sentence , `` The sentence may be as short as a few months , '' Atmaja said . The boy could also receive credit for time served . The prosecution presented two witnesses at the trial Tuesday . Rifan , the defense attorney , said he expects a quick decision in the trial , with twice-weekly court hearings that could end by mid-November . `` The boy was under stress from the media attention but was otherwise in relatively good condition during the court hearing , '' Rifan said . The teen 's next court appearance is scheduled for Friday . The teen has been detained since his October 4 arrest , after allegedly buying 3.6 grams of cannabis off the streets . He was on vacation with his parents in Bali , a popular tourist destination for many Australians . He was initially detained at a police headquarters but was recently moved to an immigration detention center . Australian officials and the teen 's lawyer lobbied intensively to have him released , but prosecutors announced last week that the minor would stand trial . Indonesia anti-drugs laws are considered strict . Visitors to the country are warned , upon arrival , that some drug crimes carry a maximum penalty of death . Still , many have been arrested and convicted for various drug offenses . Two Australians are on death row in Bali 's Kerobokan prison . Six other Australians are serving life sentences .
