I reckon supporting one nation is incredibly normalised these days. It's no longer an extreme notion (to the converted or fence sitters).
I also believe their core has grown quite a bit.
When have you ever known someone with extreme views from any side view negative information rationally? If anything the negative press will strengthen their support. They've already turned it around to being an attack on Australia's democracy by an Islamic nation. Or an attack by leftist mainstream media (this one really makes the mind boggle).
The only way this hurts them is when it comes to preference voting imo.
Apparently Australians can be swayed by facts...
