Siekman's coaching career began in earnest with two years as the Chelsea Football Club's Under 18 coach.[1]
His first major coaching appointment came when he joined the Dandenong Stingrays as a development coach in 2006.[1] He served at the TAC Cup side in multiple roles over the next decade including later as a senior assistant coach.[2]
In addition to his role at the Stingrays, Siekman served as head coach of the Victorian Metro side at Youth Girls Championships between 2014 and 2016. He coached the side to national titles in both 2015 and 2016.[3]
He also briefly worked as an assistant development coach for Collingwood's VFL team in 2008.[1]
AFL Women's
Siekman was appointed as the inaugural head coach of Collingwood's AFL Women's side in July 2016.[3]
He coached the side to three wins from seven matches in the league's inaugural season in 2017, followed by three wins in 2018, and only one win in 2019. Siekman was sacked by Collingwood after coaching the side to a wooden spoon and just one win in the 2019 season.[4]
