Australian teenager Jamie Murphy's nightmare in Bali, where he was locked up for two nights and faced years of jail time, is over after he landed home in Perth.
Airport staff whisked the 18-year-old and his parents Brendan and Anna Murphy through a private exit to a waiting van to avoid the media.
Murphy achieved national infamy this week when news broke of his arrest early on Tuesday outside the Kuta nightclub Sky Garden for carrying a bag of white powder.
Film emerged of him being physically roughed up by a security guard who appeared to be choking him and squashing his face, as a distressed Murphy pleaded "it's not mine ... what are you doing?"

Australian media captured his arrest because they were in Bali to cover large numbers of schoolies celebrating finishing high school.
Murphy finished school last year but arrived in Bali on Sunday night with two friends celebrating graduation.
Australian Foreign Minister Julie Bishop responded by urging young Australians not to break local laws overseas.
Police said they suspected the 1.6 grams of white powder he was caught with was heroin or cocaine - an offence that carries with it a maximum of 12 years in prison.
But by Wednesday afternoon, they said the test results of both the powder and the teenager's urine had come back negative and he was released from Kuta police station that night.
Kuta police chief Wayan Sumara told reporters the powder turned out to be a mixture of painkillers, caffeine, cold and flu medication and cough medication.
Describing Murphy as "very lucky", he said the teen had bought it off a man on the street who told him it would "make him feel good".
"Someone offered him something, he wanted to try it ... He is just a teenager, he wanted to know what it is," he said.
"He tried it in the room, he drank, mixed it together,"
"This made him feel nauseous."
"I don't want to say whether he is stupid or not."
Sky Garden apologised for the "excessive force" used during his detainment.
They said the security involved in the teenager's detainment has been "reprimanded" and will not be permitted to return to work until completing further training.
