Anthony John Michael "Rooster" Perish (born 1970) is a convicted Australian murderer from Leppington New South Wales, known to have killed a Sydney drug dealer, Terry Falconer, in 2001. He may also be responsible for other killings. Ostensibly, Falconer's murder occurred because Falconer is alleged to have murdered Perish's elderly grandparents, Anthony Perish Sr. (1902-1993) and Frances Perish (1900-1993), in 1993.
Together with his brother, Andrew Perish, and other members of his criminal gang, as well as outlaw motorcycle clubs, Perish and associates are estimated to be responsible for at least six murders and two suspicious deaths. Altogether, the Terry Falconer/Perish gang murder investigation took over a decade and involved fourteen people, who are estimated to have committed at least one hundred separate offences that involve amphetamine and methamphetamine drug dealing, assault, abduction, murder and manslaughter Perish and his collaborators were apprehended in 2008 and went to trial in April 2012, resulting in Anthony Perish (42) being sentenced to eighteen years imprisonment, while his brother Andrew Perish (41) was sentenced to nine years and an associate, Matthew Lawton was sentenced to fifteen years, each on murder and conspiracy charges.
In 1993, Anthony and Andrew Perish's grandparents were murdered at their Leppington home, possibly by Terry Falconer, a Sydney drug dealer. At that time, Anthony had already begun his criminal career and was already wanted for manufacturing amphetamines and supplying the drug to others. For the next fourteen years (1993-2007), Anthony evaded justice as an itinerant, periodically relocating to Turramurra and Girvan in New South Wales, and South Australia. During his period in South Australia, he resumed production and distribution of amphetamine and methamphetamine, in conjunction with disgraced former solicitor Justin Birk Hill.
