A lot of the hyper-focused micro parties are actually feeder organisations for the bigger far right parties. Not just for people and money, but for preference votes.
This is a lower house election; the real swarms of microparties show up in the upper house ballots.
Thanks to the way that preferential proportional voting works, it’s possible for a party to elect a Senator with a miniscule primary vote if they manage to arrange preference flows from a large number of other parties. Obscure single issue parties tend to draw a fair number of early preferences from cranky low-info protest voters, and they make a substantial total when combined.
