Perth man jailed in Bali over passport misuse
Shaun Davidson, arrested in Bali for using another man's passport, has been sentenced to a year behind bars at Kerobokan jail.
"It [Kerobokan jail] was built for 300 prisoners, there are1200 there," Davidson said.
"The first couple of weeks you get there, there are 20 other people here in the cell the size of this area here," he said, gesturing to the tiny holding cell crammed with prisoners outside Denpasar District Court.
"No beds, no nothing, you don't get given anything. Just like concrete floors. In the corner they have got a bit blocked off where there is a hole in the ground. That's pretty much the toilet and the shower."
He said prisoners were not even given a mat.
However, Davidson said conditions were bearable if you had money and support from the outside.
"My sister has been the biggest help, she's been over here for a bit, she was here today, she helped me with money."
Davidson was due to face Perth Magistrates Court on January 28 last year, charged with possessing methamphetamine and cannabis and two other offences.
When he didn't attend, an arrest warrant was issued.
But instead of going to court, Davidson skipped the country, arriving in Indonesia on a one-month tourist visa,
Davidson said he lost his passport. He said he had contacted the Australian passport office and reported his own missing but then began using a passport under the name of Michael John Bayman, which Davidson said he had found in a hotel room.
Bali immigration authorities told Fairfax Media the passport had been reported missing by the real owner in 2013.
Davidson spent the year in Bali boxing and partying.
But he came to the attention of authorities in March when he was staying at Rabasta Hotel in Kuta.
Ngurah Rai airport immigration officer Mohamad Soleh told Fairfax Media in April that a report was made of a foreigner staying in Kuta who was suspected of overstaying his visa.
When immigration authorities investigated, they found he had not only overstayed his visa but was using a fake identity.
Mr Soleh said the Australian government and Australian Federal Police had confirmed Davidson's real identity.
Head judge Made Pasek said on Thursday he found Davidson "convincingly guilty" of misusing a travel document belonging to someone else.
He sentenced him to one year jail, minus the time already served, and a 100 million rupiah ($AUD10,000) fine or additional five months in jail.
Mr Pasek said mitigating factors were that Davidson had been polite during his trial and admitted his guilt.
However had used fake documents and what he had done was harmful to Indonesia.
Davidson said he thought it was a fair judgement and he would serve the extra five months instead of paying the fine.
"It's not what I was hoping for of course, but everyone knows the legal system here. I didn't conform to the legal system. I didn't pay any money, I did my defence myself."
He said he would continue to teach boxing inside Kerobokan jail.
"I have about 15 to 20 people I train in boxing, so that's pretty good. I guess it gives the locals something to do. It gives them something to look forward to. It's pretty hard for some of the locals - if you don't have money to get food you don't eat."
