Comancheros boss Mark Buddle has been extradited from Darwin to Melbourne to face court over the alleged importation of $40 million worth of cocaine into Australia.
The Australian Federal Police (AFP) said officers escorted the 37-year-old on a chartered flight from Darwin to Melbourne this morning.
It is the final move in a series of extraditions.
Mr Buddle was taken into custody by AFP officers in Darwin earlier this week after being extradited to Australia by Turkish authorities.
He was deported to Turkey from Northern Cyprus last month, and taken into police custody in the capital, Ankara.
Mr Buddle is understood to have left Australia in 2016.
He had been living in the self-declared republic of Northern Cyprus after being granted a residency permit in August 2021.
The area declared its independence in 1983 but is recognised by only one of the United Nations' 193 member states, Turkey.
Mr Buddle became president of the Comanchero Outlaw Motorcycle Gang in 2010 when former leader Daux Hohepa Ngakuru left Australia.
He was understood to have been leading the Comanchero Motorcycle Club while living overseas.
A Darwin judge on Wednesday granted a request for Mr Buddle to be extradited to Melbourne.
Now in Victoria, Mr Buddle faces two charges over the alleged importation of more than 160 kilograms of cocaine in 2021.
Both the charges of importing a commercial quantity of a border-controlled drug and conspiracy to import a commercial quantity of a border-controlled drug carry a maximum sentence of life in prison.
Mr Buddle appeared in the Melbourne Magistrates' Court this morning for a brief administrative hearing.
The 37-year-old was wearing trackpants and escorted by two guards.
He nodded at Magistrate Kieran Gilligan before taking a seat and looking around the courtroom.
Mr Buddle did not make an application for bail and was remanded in custody until his next court appearance in November.
He waved and gave a thumbs up to his lawyer as he left the courtroom.
When asked how Mr Buddle was faring in custody, Mr Buddle's defence lawyer, Stephen Zahr, said his client was "not too bad".
"For the long flight that he's just come back from," he said.
Mr Zahr, who is based in Sydney, said it was "too early" to say how his client would plead to the charges.
He was unable to say whether Mr Buddle feared for his safety.
"I don't have any information in relation to that," he said.
