That's a rare example where it can work (I don't know anything about Australia but will take your word for it). Most carbon schemes are not about subsidizing solar panels. The majority of it is very questionable as other users have pointed out with examples. Most people care about the environment and are worried about climate change. Most also understand very little about geoscience. There is a lot of pressure on governments and corporations to just do "something" about it, but few concrete demands. That's why deceptive practices and outright scams are so common, especially in so-called carbon offsetting and carbon removal schemes. Having a bit of relevant scientific background, I've sadly seen more than once how questionable carbon offset companies infiltrate communities and corporations to get them to buy in. Some of them spend a lot of time lobbying and advertising on a grassroots level to get cooperation deals. Warning folks has not worked in the cases I've tried because as soon as you question it you're viewed as a climate skeptic who does not care about global warming and getting into hours long discussions with non-experts trying to explain to them why a certain promise can not work in reality the way it's described on the carbon credit website is pointless. Their promises and beautiful pictures of green forests and blue skies are a lot more persuasive sadly since it's professional marketing.
