Four years ago, a fresh-faced Max Chandler-Mather spoke passionately about his '18-year plan for a Greens government'.
The former union organiser and Greens firebrand said his ambitious plot relied on a simple equation: you get one vote for every three meaningful conversations you have with Australian voters.
If, he argued with hopelessly naïve logic, Greens volunteers just had 1,866,216 meaningful conversations with Australian voters, they could seize power by 2040.
His equation would deliver them a total 45 seats, making them the senior party in a Coalition with Labor on just 44.
