"It's a credit to the defence team and the expert witnesses - it's a very very strong case."
De Malmanche, 53, is in Kerobokan Prison after being arrested in December at Bali's Denpasar Airport and charged with carrying 1.7kg of methamphetamine in his backpack. He had travelled to Hong Kong to meet his internet girlfriend "Jessie" before flying to Bali.
The defence has argued that de Malmanche was set up and was a trafficked person rather than a trafficker. About 450 pages of online conversation between de Malmanche and Jessie formed a big part of the defence presented in court last week.
"He is a man who believed he was in love," Mr Bellamy said. "The major mistake was he was naive and that comes back to his mental ability and how he was interpreting information - he just wasn't reading the signs.
"Under Indonesian law, if you can prove that the person is a trafficked person then they can't be convicted of any crime."
The defence will sum up next Thursday, Mr Bellamy said.
The trial, which sits only one day a week, began in March but was delayed due to de Malmanche's angina problems.
Mr Bellamy said he and supporters were trying to keep de Malmanche thinking positive.
De Malmanche's son Shaun is also in Bali, his second trip to see his dad this year. He was in court on Thursday and told the Chronicle he felt it "went well".
"We got everything said that needed to be said. It's up to the Indonesian legal system now."
