The longtime minister said a close family member’s serious illness means he cannot keep giving Parliament the attention his role demands.
On Monday, Corrective Services Minister Paul Papalia announced his resignation from Western Australia Parliament, effective July 10, citing a close family member's serious illness.
Before entering politics in 2007, Papalia served 26 years in the Navy, including time in the Special Air Service Regiment, becoming one of Labor's most trusted ministers.
Ministerial scrutiny intensified following a report highlighting "systemic failure across multiple prisons" in Western Australia, where Inspector of Custodial Services Eamon Ryan revealed deteriorating conditions at Hakea, Casuarina, and Melaleuca.
Premier Roger Cook confirmed Labor MPs will meet this Friday for a cabinet reshuffle to fill critical roles in defence and corrective services following the resignation.
One Nation has targeted Secret Harbour as a priority seat for the by-election, though Labor won the electorate with more than 62 per cent of the vote in 2025.
