Overview
Recruited from Labrador, Queensland, Osborne debuted for Hawthorn Football Club in 2001 after being elevated from the rookie list. He played in the Box Hill Hawks's 2001 premiership team that year.[2] While only playing three games in his first two seasons, since 2003 Osborne was a regular selection when not injured. A versatile player Osborne could play as a small defender, midfielder or forward. In 2005, he was awarded the club's 'defensive pursuits player of the year'. In 2008 Osborne played in 20 of the 22 home-and-away games, and was part of Hawthorn's premiership team and finished 5th in the Peter Crimmins Medal.
Osborne suffered a season-ending ACL injury in Round 7 of the 2012 season. He was delisted at the end of the 2012 season, but was redrafted with pick 70 in 2012 draft. Hawthorn recruitment manager Graeme Wright said: "It's great to have 'Ossie' back on the list officially. He was very gracious in helping us from a list management point of view. We were able to get Jonathan Simpkin onto the list as a delisted free agent by delisting 'Ossie'."[3]
He played 5 senior games in 2013, spending most of the season with Hawthorn's affiliate VFL side Box Hill.
Osborne announced his retirement at Hawthorn's 2013 Best and Fairest count.[4]
Immediately after his playing days were over, he joined Carlton as a development coach on 27 November 2013.[5]
In March 2016, Osborne, along with ex-teammate Brad Sewell, launched the Australian Rules Football College.[6] Based in North Melbourne, and based on a US college model, the Australian Rules Football College focuses on developing the football skills of their students, whilst also placing an emphasis on education, through offering certificates in health, personal training, massage, leadership, management and diplomas in business.[7]
