Re the curse of identity politics.
In my opinion it is the principal form of politics in this time and place - and has essentially always been so.
Everybody votes according to their various identities.
Whats in it for me my family/relatives, my ethnic/racial and/or "religious" background,
my village/town/suburb/city/region, my state and country.

Even worse of course is the fact that the principal parties (liberal/labour/national) tailor their policies via the extensive use of FOCUS groups, which of course by their very nature, emphasize the whats-in-it-for-me syndrome.

More on identity politics.
Morrison was of course using the (sectarian) "religious" identity game when he was featured "worshiping" at his church during the election campaign.
Howard and Costello did the same when they attended/addressed the "religious" gabfests put on by Hillsong and (perhaps) the Australian Christian Lobby.
So too with their proposed "religious freedom" legislation.

Meanwhile the now everywhere use of social media has changed how the process of election politics now works.
The various political parties can now tailor their whats-in-it-for-me/you propaganda according to any and everyone's social media profile, especially their "religious" and ethnic/racial identities.

This process is now used all over the world, especially in the USA via the social profile data collected by Cambridge Analytica

One Nation + the Shooters, Fishers & Farmers party are now the sensible centre of Australian politics. Let that sink in & think about it for a while.

The Labor-Green Socialist Alliance is as extreme left as it gets.

The Liberal-National Closet-Communist coalition is only slightly less left wing.

Queensland has local & state elections coming up next year. The anti ALP-LNP vote will probably be even higher next time.
