The battle for the Victorian seat of Indi is shaping up as a three-way contest. Independent Cathy McGowan is trying to fend off the former member Sophie Mirabella and the Nationals' Marty Corboy.

McGowan tells Michelle Grattan the election will come down to preferences.

“I’m hoping that the National Party people will consider giving me their second preference and I’m hoping that Liberal Party people … certainly the ones in Wodonga – don’t see their answer in the National Party and they will consider giving me their preferences,” she says.

In this special election podcast, Michelle Grattan interviews McGowan, Corboy, as well as the Greens' candidate Jenny O'Connor and Labor’s Eric Kerr. Sophie Mirabella was unwilling to be interviewed.
