Morrison destroyed the lnp all on his own. He didn’t appeal to younger generations same as the Tory filth won’t. He cooked his own goose by lying incessantly and getting caught out furnishing himself (ala Boris ) and has carried on doing so even since he’s left. Don’t think you’ll see the LNP in power here again for a while. Even Murdocks control over the media didn’t save them.
As to big changes the only one I voted for and care about is the anti corruption committee being installed. Something the coalition filth fought tooth and nail to stop. It’s even back dating corruption so you’ll see plenty of the LNP getting hauled over the coals over the next few years.
