Former Prime Minister Tony Abbott’s 25-year career as the member for Warringah has been ended by independent candidate Zali Steggall.

Four Corners brings you the inside story of how the battle for Warringah was lost and won in the 2019 federal election.

In interviews with key players, Four Corners reveals the strategy behind the Steggall campaign, the roots of the insurgency within the seat of Warringah and the roles played by the key activist groups, GetUp and Advance Australia.

With Tony Abbott's political career at an end, all eyes will be on the Liberal Party to see if the divisions that roiled the last two governments are over.
