You're right - if you mean the people who live in the Federal Electoral Divisions of Denison, Melbourne, or if you're referring to the Senate (voting for the Greens, possibly Xenaphon in SA, possibly KAP in QLD, or possibly the DLP in Victoria...)
Otherwise, their vote will almost certainly go to either the Coalition or Labor on preferences.
Not sure if you're right there. Once you have done your bit by entering the polling booth, there are many choices you can make. I
am one of those tragics that number every square on the senate paper, partly so that I can put Fred Nile dead motherless last but mostly because I won't let anyone dictate where my preferences go.
But of course the main game is the House of Reps. Now I
do usually number every box here as well, but there is nothing stopping me from putting a "1" in the box of a fringe party candidate and then nowhere else. Or if I'm really in a foul mood I could simply write a message of complaint to both major parties and drop it in the ballot box, Either way my vote will not count towards the 2-party preferred allocations.
And I shouldn't generalise about Alan Jones so much, seeing as I only hear of the most extreme stuff courtesy of Media Watch, but ..... my MIL listens to him religiously and then spouts worrying lies about asylum seekers and refugees. Doesn't fill me with confidence that all Australians are getting a balanced view. Reading the Australian could only be an improvement, but anyone who thinks they don't have a conservative bias is quite delusional.
I was actually shocked the first time I saw Janet Albrectsen on Q&A. Having extreme right-wing commentators is one thing (the SMH had Miranda Devine for a while!), but dressing it up as editorial commentary is a bit rich. Here is a sample of her work :-

Balanced? - you be the judge, but if all you read is The Australian then perhaps you should disqualify yourself.
