He was recruited with pick #29 in the 2011 Rookie Draft, having played as a small forward for the South Fremantle Football Club in the WAFL. Prior to round 4 of the 2012 AFL season he was elevated to the senior list to replace Brent Prismall who was on the long-term injury list with an ACL injury. He made his debut that weekend against Carlton, starting the game as the substitute player and replacing Michael Hurley in the third quarter. He was delisted by Essendon at the end of the 2014 season after only playing three games in 2013 and five in 2014.
On 12 January 2016 Dell'Olio was named as one of 34 past and present Essendon players found guilty over their use of illegal supplements during the 2012 AFL season. As a result, Dell'Olio was suspended from playing at all levels for twelve months, effective from November 2015.
