The online event brought together 300 people, with member for Indi Helen Haines, Zali Steggall, Professor Kerryn Phelps, Jacqui Lambie, Ali Cupper and Suzanna Sheed among the guest speakers.

Regional leader and businesswoman Susan Benedyka announced her tilt for a Victorian Senate seat.

Ms McGowan said she was overwhelmed by the interest in the convention.

"The rising interest in community independents isn't surprising given the ongoing disillusionment with Australian politics," she said.

"People want and expect better from their elected representatives, and that's a key reason we're seeing more community leaders like Susan Benedyka step forward as candidates and campaigners and an increasing number of people coming together to create community 'voices' groups.

"The convention was designed to spark and support the national grassroots movement of 'voices for' by connecting individuals and 'voices for' groups from across the country, and to help guide communities to select and get behind the election of their own leaders to state or federal parliament, and even local government."
