Police officer Cok Putra Sutrisna told the court Ormsby, who was staying at another villa, arrived in the early morning by motorbike, looking dishevelled.
"Her physical appearance looked messy with her hair uncombed," he said. "She looked like a drunk person."
Police officer Made Sudiarsa said they approached Ormsby as she was opening the villa door with a key.
When they found the joint in her handbag, the former Paddington shop assistant admitted it was for her own use, the court heard.
But when drugs were found in a cupboard drawer — "a black chunk of something, a big capsule and four small capsules" — Ormsby said they weren't hers.
Brig Sudiarsa confirmed reports a man named Marco, believed to be Ormsby's Australian ex-lover, then turned up.
"We then searched him and we found nothing, that's why he was released," he told the court.
After the raid, police promised to pursue the other people who had been at the villa, who had all since left the holiday island.
Instead, Ormsby's lawyer Ari Soenardi says they kept his client in custody for three months without charges, trying to link her to the other drugs.
Ormsby was relaxed in court on Thursday, wearing a loose-fitting white shirt and carrying a fan that said: "Paradise".
Through a translator, she told the court she didn't disagree with the police evidence.
Mr Soenardi says he will ask the court to treat Ormsby as a drug user and consider leniency when sentencing her.
The trial continues next week.
