It's the natural Conservative position. They oppose progress at all costs. The Greens are focused on progress. It's policy-driven for the Libs (when they know what they believe in).A fair bit of this is about the optics. All of the LNP and a decent few in Labor have become persuaded that publicly aligning themselves with the greens is electoral poison. Dumb on both parts, particularly Labor whose voter base is less concerned about the matter.
Necessary for the libs who have run a scare campaign for so long that they can’t even contemplate compromise. And of course, in being that way, they left what they thought were blue ribbon seats open for the teals to just pluck out of their hands.
Fear of the Greens is utterly unreal.
For the ALP, it's typical pragmatism. The only group that the ALP will fight harder than the Greens are other factions within the ALP. They don't care about the policy outcome, they care about power.
