Rather than specific band/performer I'd have a run through

Triple J's Hottest Australian songs of all time. Of course, it's highly debatable, and may have recency bias

For a different -and maybe much broader- take worth checking out is this mix. It's only about 2 hours long and takes a popular Aussie song of each year from 1971 to 2026. You will hear songs that would never be recommended to you otherwise, though you have to put up with that guy lol. I shouldn't be disrespectful, he's done a huge job even in just putting that all together

If you can pick out some songs you like, then you can go down the artists path, and then find similar artists. Good luck
