Climate change and environmental collapse are somewhat larger dimensions than smoking though, both in impact as well as required policy changes.

The tobacco industry has never had a particular good reputation, so getting social buy-in is not that hard. It has no more utility than the alcohol industry, so getting rid of it has not a lot of knock-on effects. Even then, demanding a few scary pictures was a slap on the wrist, compared to outright banning them. (Not sure about Australia, but other notions actually work with local bans in a gradually increasing number of locations)

I think fighting climate change and environmental collapse are harder problems because the responsible industries are deeply intertwined into our economic systems and lifestyles. They are also providing a significant amount of political power. We'll have to actively work to find alternative ways of doing things in many areas before we're able to scale back here.
