I wonder how the Shooters Party (is that the correct name?) did? I’ve heard that they have wanted to hold the balance of power and do similar things to make the voices of law abiding gun owners there heard by the other parties.
In my state of Victoria, they currently sit at 13th out of 38 with 0.1320 of a quota after first preferences. I'm not going to even try to explain exactly what that means :) but in simple terms, you want to be in the top third after first preferences to have a chance. They are just at that level (technically they'd want to be 12th rather than 13th to be in the top third, but they are only 7 votes behind the 12th so I'd call that a tie really.)
In NSW, they are 7 out of 41 with .2515 of a quota - that's not bad at all.
In Queensland, 10th out of 39 with .1343 of a quota - in the ball park.
In Western Australia, 7th out of 29 with .2292 of a quota. Pretty healthy.
In South Australia, 9th out of 25 with .0898 of a quota. Realistically not likely.
In Tasmania, 9th out of 23 with 0.1678 of a quota. Probably too far down the list to be realistic but not impossible.
It will all come down to preferences and that can be really complex and will be at least a week before we know. But they are not in a bad position. Realistically I think their best chance for a Senator is probably in WA. And even a single Senator has to be listened to.
