Oliver John Flinn O'Halloran (born 28 April 2000) is an Australian aviator living in Hobart, Tasmania. He is best known for his solo flight around Australia which previously made him the youngest person to circumnavigate Australia, solo and unassisted, which he did in a bid to encourage others to pursue ambitious dreams and promote aviation to youths. O'Halloran began flying in late 2014, but had to wait till he was 17 years of age to attempt the record due to Civil Aviation Safety Authority regulations.
