It is understood Picard agreed to go of his own accord after losing his visa appeal in the Federal Court in December. With no visa the penniless, sick, "retired" bikie boss had few options.
In 2010, Tasmania police began investigating the organised trafficking of methamphetamine into Tasmania and found a network which saw drugs sourced from the mainland and on-sold to Picard.
After he admitted trafficking 1kg of meth with a street value estimated at between A$128,000 ($136,555) and A$504,400, he was sentenced to three years jail, 18 months non-parole, in 2013.
Australian Immigration Minister Peter Dutton said: "Mr Picard represents an unacceptable risk of harm to the Australian community."
