Initially a solo project of Peter Michael Peric (of Syphilis/ex-Automation/ex-Deadspawn; guitar), with Aaron Bilbija (guitar), Andrew Lilley (guitar) and, Jonah Weingarten (keyboard) assisting, the recorded works quickly caught the attention of numerous well known musicians involved in the Australian Metal scene including Grahame Goode (ex-Automation/ex-Neophobia/ex-Cryogenic; drums), Jamie Stinson (a.k.a. Astennu; ex-Dimmu Borgir/ex-Lord Kaos; guitar), Lee Glanzmann (of Syphilis; bass) and Joss Separovic (of Samsaras Wound/of Shackles; vocals); all of whom would soon become permanent members of the operation.
Two months after the band's founding, Infernal Method played their first and somewhat controversial performance at Australia's Metal for the Brain 11. April 2002 saw the band perform at Big God's Metal Massacre 2 in Melbourne, with Chalice, Vanishing Point and Hellspawn. A 3-song Demo CD featuring the band's initial works titled Demo 2002 (2002) was released in May, 2002.
The band split up in July 2004 when Peric and Goode moved on to Dungeon. The band then reformed when the pair returned from Dungeon in January 2005.
Late October 2005 Infernal Method signed to 'Ward 69' records to release their debut album, Architecture of Instinct (2005), now re-recorded with new vocalist Evan Williams after the band reformed in 2005.
In 2006, Peric temporarily departed the band, replaced by Andrew Najdek on lead guitar before deciding to return. Soon after, vocalist Williams left to be replaced by the returning Najdek.
March 2007 Infernal Method announced they had disbanded following the departure of the two guitarists.
