We have four Major Parties - Labor, the Liberals, the Nationals, and the Greens. If you understand their relative power based on our system of government, you’ll see that we’re somewhere in between the US and the EU with regards to representational democracy. It’s not great, but in the Anglospheric context we do pretty well because the others don’t have our combination of Ranked Choice Voting (RCV), Proportional Representative Voting (PRV) and Mandatory Voting.
