Siekman made history with the Magpies by leading them into the AFLW competition during that famous night at Ikon Park in 2017.

Being the first coach, he also took on the responsibility of building a first class and lasting female football program.

“I’m very proud to have been involved in the creation of Collingwood’s AFLW operation,” Siekman said.

“The entire program was built from the ground up and it was a wonderful personal and professional privilege to share in.

“I owe so much to the players and staff who contributed to what will be seen in time as the foundation years of not only Collingwood’s AFLW program but the AFLW competition itself."

In Collingwood's inaugural season, they finished fifth before coming in sixth last season. 

With the introduction of the new conference season in 2019, Collingwood were placed alongside Brisbane, Carlton, Geelong and GWS.

The side managed just a single win all season and that came against the Brisbane Lions in the final round of the season.

The process of choosing Siekman’s successor as AFLW senior coach will commence immediately.
