"Freedom Parties" Did Not Cost One Nation A WA Senate Seat

Sometimes I find items of interest in the oddest ways.  Today I was searching for tweets about WA Labor (as of 3:45 pm) Senator Fatima Payman in connection with her possible stance on a Greens motion that the Senate consider recognition of Palestine to be a matter of urgency.  I found this tweet by Mark Rowley, to which he links a video in which he tells Pauline Hanson how One Nation was diddled out of a 6th Senate seat by "freedom friendly" micro-parties, hence blaming them for the election of Payman.  

I thought this was an interesting thing to look into.  I find that minor right wing media is often a hotbed for incorrect claims about the electoral system and election results and this case is no different.  

Payman won the 6th Western Australian Senate seat over Filing by a margin of 23490 votes.  Rowley's video singles out three particular micro-parties, the Great Australian Party (led by former One Nation Senator Rod Culleton, who was disqualified from the Senate in 2017), the so-called "Informed Medical Options Party" (IMOP) and the Australian Federation Party.   These parties between them polled 27791 primary votes.  Rowley says that if these parties had voted for "the likes of One Nation" (are there any likes besides One Nation itself?) the party "would have been looking at a 6th Senate position".
