https://opennem.org.au/energy/sa1/ is the one-stop-shop for current energy situation in Australia.
Anecdotal: SA was pushing towards clean energy notably before the battery came in, but in turn, had a very unstable grid, and the things like energy trading et al. were tied up in international ownership iirc (needing authorization to do a large energy trade required someone from France giving approval, timezones didn't match up, and the grid fully shut down for a significant period of time)
After the battery was put in and operational, (noting that other things may also have been happening that I'm not aware of), the grid ended up being a lot more stable. Almost a night-and-day feeling to the change.
Overall the local sentiment about it is "electricity is too expensive", https://www.abc.net.au/news/2023-03-15/australian-energy-reg... A very hot topic.
