Dominic Perrottet, former New South Wales Premier, announced his retirement from politics after 13 years of service, citing it as an honor and privilege to represent the people of NSW. His departure follows a transition to a role in Washington DC as the US head of corporate and external relations for BHP. Perrottet played crucial roles during the COVID-19 pandemic, including steering the state's response and advocating for reopening and financial support. His resignation triggers a by-election in Epping and the Liberal-held seat of Hornsby, following the departure of another MP. Perrottet's career, from treasurer to premier, marked by challenges, culminates in a move to the private sector, emphasizing contributions to BHP's global standing.
