Word from The Hill: Australia's new Deputy Prime Minister Barnaby Joyce, climate policy and UNESCO

As well as Michelle Grattan’s usual interviews with experts and politicians about the news of the day, Politics with Michelle Grattan now includes “Word from The Hill”, where all things political will be discussed with members of The Conversations’s politics team.

In this episode, politics + society editor Amanda Dunn and Michelle dive into the National party spill, which resulted in Barnaby Joyce grabbing back his old leadership job, what this means for the Nationals at the election, and the climate change policy position this puts Scott Morrison in.

They also discuss the recommendation by UNESCO to list the Great Barrier Reef as "in danger", and the suggestion by the government this classification was politically motivated.
