On Saturday, residents in the Melbourne electorate of Aston will vote to decide which candidate should replace the former Liberal cabinet minister Alan Tudge, who held the seat for 13 years. The byelection has been cast as Peter Dutton’s first major test as federal opposition leader in a state where the Liberal party recently lost its third election in a row. Chief political correspondent Paul Karp joins Jane Lee to discuss the battle for Aston, what it means for Peter Dutton and how people in the area are thinking about their vote.
