Jake Mastroianni, 26, will be kept in Bangkok's notorious Klong Prem jail in Bangkok where up to 30 prisoners share cells in conditions described as harsh.

Mastroianni appeared shackled in a Bangkok court on Tuesday with a 28-year-old former British soldier, Lance Whitmore, who lost his appeal on a 50-year sentence.

Mastroianni was arrested in Pattaya in August 2014 with 61 ecstasy pills and Whitmore with 200. Pattaya, a city three hours drive from Bangkok, has dozens of late night clubs and is known as Thailand's "sin city".

Mastroianni's Facebook page under the stage name "Badmouth" shows that he was a regular at Sydney clubs in 2013, before he arrived in Thailand.

In 2014 he worked as a DJ at Thailand's famous "full moon" party on Koh Phangan in the Gulf of Thailand.

The Sapphire club in Pattaya's Walking Street announced in May 2014 that Badmouth would make his final appearance as guest DJ before he returned to live in Australia. He was arrested in three months later.

Whitmore's sentence was half as long as Mastroianni's because he pleaded guilty last year.

Nathan Feeney, a legal consultant for Mastroianni told The Guardian his client would have received a much lighter sentence if he had pleaded guilty but his previous lawyers advised him not to.

Jeffrey Stevens, a lawyer acting for both men, said he was disappointed by what he said was a severe sentence.

"Everyone was hoping the sentence would be reduced further," he said.

Mastroianni's harsh sentence means he can apply to be transferred to an Australian prison in six years.

Friends and family of Whitmore have set-up a fundraising campaign to help him.

The Department of Foreign Affairs said it was providing consular assistance to an Australian man imprisoned in Thailand.
