Tony Windsor was a politician, and as an independent helped hand Julia Gillard minority government and the prime ministership.

Despite being a politician, he says that at the end of the day, politicians are, by their nature, weak. And if there’s any example that’s taught him that, it’s the decades-long fight over our water and how we protect it.

As the election tightens, there is a very real possibility that neither major party wins the 76-seat majority they need to govern in their own right. For independents in this scenario, it’s an enormous choice – who do they support, what do they ask for, and who do they make prime minister? Today, we speak to someone who has made that choice, former Independent Tony Windsor, on how to navigate a hung parliament and how Scott Morrison and Anthony Albanese would act in those negotiations.
