He has been a National Party member of the Victorian Legislative Assembly since 2010, representing the electorate of Gippsland East.

He also captain coached the East Gippsland Football League (EGFL) interleague team and is a 100-goal kicker in a season.

His interests include spending time in the outdoors with his family fishing and camping, continuing to push for better disability services in rural areas, and "having some fun" as co-host of a local community radio sports show.

In more recent years Bull has trekked the Kokoda Trail on five occasions, accompanying Year 11 scholarship winning students from his local area, to walk in the footsteps of those from the East Gippsland community who served and in several cases, gave their lives.

As part of the Coalition's election victory over John Brumby's Labor government, Bull ousted the sitting member, Independent Craig Ingram, with a 20-point two-candidate preferred swing, returning the seat to the National Party.
