The by-election resulted in the Liberal Party losing the seat to Independent candidate Alex McTaggart.
[1] Brogden owned up to his behaviour on the morning of the 29 August, although it was not until the afternoon of the same day that he announced his resignation as leader of the party.
[2] When he stepped down as leader, Brogden announced that he would remain a member of parliament, describing his future role as that of a "middle-bencher".
However, a strong challenge was presented in the form of Pittwater Council Mayor Alex McTaggart, running as an independent.
At the by-election, McTaggart defeated Liberal candidate Paul Nicolaou in what was widely considered a shock result.
