That’s a benefit of minority governments. Being forced to work with the Cross-bench. The results look like it might be only be one short, so the ALP can pick and choose who to work with/get the final vote for, (in the lower house)
Anecdote. Canada (I lived there for several years), has a first past the post system in the equivalent of their lower house. No preferential voting.
So if four people run, one can get elected with 26% of the vote. (Generally you have three contenders: Conservative centre/centre-left and more left. The Conservatives like this as its posits the more progressive vote)
The outcome is you can have wild variations in government, Going from a large majority to losing most seats next election.
