The drug trial of Kiwi Myra Williams has kicked off in Bali.
The 27-year-old Taupo woman was arrested in August last year for alleged methamphetamine possession and drug trafficking.
Williams says she's been trying to pass the time behind bars in the notorious Kerobokan prison.
"I got given a guitar so I'm learning to play the guitar properly."
She faces up to 12 years behind bars and an $800,000 fine.
William flew to Bali from Melbourne on an AirAsia flight. On arrival police allege they found 0.43 grams of meth in her possession.
Before being led to her cell, she appeared to make a confession, burying her head in her hands as she apologised.
"I'm sorry to the Bali Government because I didn't respect their rules."
After her first day in Denpasar Court, she told media others should learn from her mistakes.
"Don't do drugs. Don't do drugs, just be safe."
