Barnaby Joyce’s comments that victims of the devastating NSW bushfires were likely Greens voters have been described as “absolutely disgraceful” by friends of one of the men who died.

As dozens of fires burned out-of-control across NSW on Tuesday, the former deputy prime minister took to Sky News, where he hypothesised the voting histories of two of the three people killed over the weekend.

Mr Joyce also criticised the Greens for arguing the “spurious links” between the unprecedented fires ravaging the state and climate change.

"I acknowledge that the two people who died were most likely people who voted for the Green party so I am not going to start attacking them, that's the last thing I want to do," Mr Joyce said.
