“I feel incredibly proud. I'm humbled by the vote because we worked so hard in the evenings and the weekends and I think that's what made the difference.

"Myself and quite a few of us are new to this, and we’re constantly learning, but we’re very proud that we’ve got the major parties on their toes.”
