Pederick won Hammond from Liberal-turned-independent Peter Lewis who left to contest a seat in the Upper House.
Previous to his election in to politics, Pederick managed a family dryland and grazing enterprise property at Coomandook for the past 14 years and is a supporter of local and regional community causes and events.
"[3]In June 2015, Pederick went on a fracking fact-finding trip to the US with fellow South Australian politicians Troy Bell, Mark Parnell and John Darley,[4] and farmer David Smith.
Arctocephalus forsteri, which is native to South Australia is protected as a marine mammal listed under the National Parks and Wildlife Act 1973.
[9] In August 2014 Pederick introduced a law that would allow the opportunity for foster carers to be recognised on death certificates of children who die while in their care, and be involved in their funeral arrangements.
Pederick designed the law after meeting one of his constituents, Monica Perrett, who was denied any information about her foster son Finn's death as she was not the biological mother.
Pederick was one of a group who were cleared from further enquiry by the Independent Commissioner Against Corruption (ICAC) in a public announcement by Ann Vanstone on 15 October 2020.
