Australia's most wanted fugitive had been living under the alias of 'Josh Lawson' while on the run, police say.
Biometric testing was needed to confirm the identity of fugitive Graham Gene Potter who evaded capture for more than a decade.
The 12-year manhunt for the convicted killer ended in Far North Queensland on Monday when detectives found the 64-year-old at a home in the Tablelands region.
Potter initially used the pseudonym 'Josh Lawson' when police arrived at the Ravenshoe address, about two hours south of Cairns, Detective Inspector Kevin Goan said on Tuesday.
Detectives believe Graham Potter initially used the pseudonym 'Josh Lawson' when they found him in a hide-out a Ravenshoe address, about two hours south of Cairns
But detectives involved with the case for several years had enough cause to arrest him anyway.
'They had reasonable cause to effect his arrest, bring him into custody (and) do the biometric testing through the live-scan machine,' Det Insp Goan said.
The results confirmed that 'Josh Lawson was in fact Graham Gene Potter'.
Potter has been wanted since 2010 after he allegedly failed to appear at Melbourne Magistrates Court on charges of conspiracy to murder and Commonwealth drug offences.
Police have previously attended the address where Potter was eventually found, but said 'our approach on this occasion was different'.
'The credible information that came through to investigators was sufficient …for them to gain lawful entry to the premises,' Det Insp Goan said.
Potter had evaded police for 12 years before he was located at the far north Queensland property
While he's been 'keeping a low profile', police said he had assimilated with some members of the local community.
No one has been charged in connection with Potter's hiding spot.
Potter was allegedly hired in 2008 to kill a man at a wedding of the son of Melbourne underworld figure, Mick Gatto.
He also faces charges over a $440 million ecstasy and cocaine haul the same year.
Potter served 15 years in jail for the 1981 mutilation and murder of NSW woman Kim Barry.
He was known to use disguises, such as wigs and fat suits, and there were several unconfirmed sightings over the years.
Potter was previously spotted by police at Tully, in North Queensland, in August 2010 but escaped.
Victorian police are on route to Mareeba and Potter is expected to face an extradition hearing on Tuesday.
'It's likely that he will be remanded into their custody to appear back in Victoria in the coming days,' Det Insp Goan said.
Beer bottles in the window, piles of cardboard boxes and Australia's most wanted man on top of a chicken coop: Inside rubbish-strewn home where fugitive who beheaded a teenage girl was finally found after evading cops for 12 yearsAustralia's most wanted fugitive was living in a rubbish-strewn house full of animal cages and junk when police finally tracked him down.
Graham Potter, 64, was arrested on Monday after spending more than a decade on the run.
He had allegedly skipped bail on charges in Melbourne for conspiracy to murder in 2010 and is accused of evading authorities by constantly changing his appearance.
In body-worn vision released by Queensland police during the raid to capture Potter, the shocking condition of the house in which he hid out at Ascham St, Ravenshoe, 120km south-west of Cairns in far north Queensland, was revealed.
The footage shows police locating Potter in a squalid room filled with empty cardboard boxes, a chicken coop and old bed.
Potter is seen hiding behind a bunk bed topped with multiple old mattresses. There are large cobwebs on the walls.
'This is the police. Do not move. Put your hands where I can see them,' a police officer yells at him.
'Yeah, yeah,' Potter nonchalantly responds.
