I suspect the #LNP vote has (permanently) fragmented. The loony right (ie, boomer supporters) have moved to One Nation and it is the sliver of the electorate that the elected clowns(Hastie and Sideshow Bob) think they should be chasing.
There is also a subset of 25-45 year old men who traditionally vote LNP and who have drunk too much of the X cool aid (and think Elon Musk is a good idea*) who think One Nation is a good idea.
- Elon Musk is a grifter who has never been the primary source of any good idea in his life time.
