He was eventually bailed just before Christmas and pleaded guilty to two counts of supplying an indictable quantity of drugs other than cannabis, one count of supplying prohibited drugs and one count of supplying a small quantity of drugs.
Police say he was selling the drugs to friends and tourists in the Byron Bay area.
The Nine Network's A Current Affair broadcast vision of Brown last night waxing his surfboard near his parent's home.
He refused to comment when approached by the ACA crew.
"Not today mate," he said, before adding: "Have a good weekend guys."
After his arrest police told the Byron Bay Local Court they were so concerned about his alleged activities they set up taskforce Strike Force ARBDO four months earlier to target him.
The prosecution told the court the teen and his customers referred to drug meets as "lunch, coffee, pool or beer" in text messages and met in person to discuss deals, reported The Gold Coast Bulletin.
Undercover detectives say one deal was 55 grams of MDMA, worth $6600, with the ecstasy being recorded at 78 per cent purity.
Brown was "living beyond his means", regularly eating out, drinking in hotels and gambling, the court was told.
Strike Force ARBDO began in late August and officers engaged in several undercover drug purchases and intercepted 7700 phone calls and text messages in a three-and-a-half-month period.
Police said they witnessed Brown yelling that "he was temporarily broke because he hadn't done any deals that day."
When police raided Brown's bedroom at his family home, they found drugs hidden in his bedroom.
