Palaszczuk taxed the coal mining companies

Sure, but it wasn't an especially bold proposal. And it wasn't particularly central to either party's election campaign, compared to things like cost of living, the Olympics, and "youth crime".

she then put in a carbon tax

Not a carbon tax. A fixed-price period leading into a cap and trade scheme.

said carbon tax only lasted a few years

Still not a carbon tax. It lasted only a few years because the Government lost at the next election. Something that was greatly aided by the constant white-anting by Rudd after he lost the leadership.

Gillard's scheme was actually working. It was world-leading legislation that actually reduced emissions while it was in effect. If Rudd had just been willing to compromise and had delivered that exact policy in 2009 instead of trying to act the Big Tough Guy and insisting it was His Way or the Highway (despite the fact that "his way" would not have reduced emissions for another decade from today), turning it into the political football that brought down both his and Gillard's Governments.

Just loose wording from me. What I was trying to say is that their vote count was actually higher this time around, not lower, but the increase was so small it was a rounding error on their overall percentage. The point being, their voterbase didn't go anywhere, but nor did they attract new folk.

Many NGO's were prepared to hit the ground running with the HAFF funding, by blocking the HAFF the Greens screwed up the prepared contracts. They delayed much needed housing for people genuinely in need by years just so they could get brownie points with renters.

On the minimum payout, Labor conceded on that point immediately. The Greens were not voting against it on those grounds.

And before you say Labor should've made concessions, the Greens unlike Labor don't actually face any electoral pressures since they have less than zero chance of forming government and basically zero chance of losing senate seats. The Greens, for good reason, have become politically toxic to deal with because they think acting like whiny children makes them charismatic. If Labor met the Greens $10 billion spending demands, it would've been used as a campaign point in this year's election and Labor would've lost to the LNP who would've then cut the HAFF.
