One of the announcers said Labor “was getting killed by the palmer united party and one nation”, what is the story there
Basically Palmer United and One Nation (and to a lesser extent the Katter Australian Party) are particularly strong in Queensland. And if people vote for them, in the end, most of their preferences will pass to the Coalition. So Labor can poll very well compared to the Coalition, but if Palmer/ONP/Katter votes are big enough, they lose in the end.
Labor gets some of the same benefit from Greens votes, but those tend to be less significant in Queensland.
It applies in other places as well, but I think that comment was largely about why Labor is not seeing gains in Queensland (I heard it as well and that was my impression).
