I've obviously come from a health background. I was a doctor before I became a pollie and one of the things I'd like to do is to really build on the world-class health system we've got. I'm passionate about climate change because it's also a health issue.

There are so many things that we need to do to reform our Parliament and I think it's bigger than that. It's all about the sort of leadership that people are getting at the moment. They're fed up with this sorta day-to-day bickering, not putting the national interest ahead of these narrow partisan interests.

If there's anything I can do, it's to present an alternative vision for the country.

I'll always put policy ahead of politics and I think people expect that. They're sick of the politics getting in the way of decent outcomes for people.
