Adelaide metalcore band I Killed the Prom Queen has been detained in Malaysia after promoters failed to organise necessary visas.

The five-piece band was due to finish its Beloved South East Asia tour on Sunday night in Solo, Indonesia, and had just performed in Kuala Lumpur when members were detained.

Guitarist Jona Weinhofen tweeted on Sunday that the band could be detained for up to 14 days.

"Apparently we're going to be detained for 4-14 days in a Malaysian immigration detention centre," he wrote.

Weinhofen also tweeted that the band was being well looked after.

"At least we have food and water and we are in good health. Things could definitely be worse and our situation pales to other recent events," he wrote.

Weinhofen said one of the immigration officials was a fan and had even asked for the members for an autograph.

"Weirdest part is some of the immigration officers asked us to autograph stuff and one wearing a prom queen shirt. Still locking us up tho [sic]," he added.

A Department of Foreign Affairs and Trade spokesperson said it was providing consular assistance to the band, "including maintaining contact with their families in Australia".

"We will not comment further due to our privacy obligations," she said.

I Killed the Prom Queen formed in 2000, but had a three-year hiatus before reforming in 2011.

The band's line up has changed over the years although Weinhofen was one of the founding members.
