Country has a large state capture problem from largely mining companies but also other special interests that have lobbied and . Anything that might threaten those interests is being pretty heavily targeted, including action on climate[0] (See "Gas led recovery", and the use of funds intended to renewables used for things like CCS/CCUS and "blue" hydrogen.). And this is bleeding into laws and enforcement.
Then there is the constant resistance to a federal anti-corruption agency as well as reducing the influence of money on federal politicians (see backbencher/ministers resolving door with lobbying firms).
The conclusion I've (sadly) come to, is that (in the short term at least) more money needs to be thrown at smaller parties and independents to try to combat this. Unlike the USA, Australia has precedent of minority governments and compulsory voting combined with a preference system means that gaining even a small number of lower house/senate seats can make a disproportional impact to the policies being set around Australia. Both major parties are so similar but just switching from Blue to Red is unlikely to result significant change in policies for some of the issues you've raised.
