Not related to my work at all. It is primarily aimed at sustainability in your own life and community, although there are also some more scientific subjects available in things like climate change. I've done subjects about gardening, home and landscape design for climate, increasing biodiversity and preparing for bushfires. It's been very interesting. It's also free under a HECS waiver, so you use the govt. credits towards the course but don't pay anything yourself. If you are wanting to go on to do study in that area it would be a good option and some of the subjects can be used for credits towards a bachelor degree.

Someone on the Melbourne Reddit sub mentioned doing it and I'm glad they did, I got a bit over it by the end but it has been good to do. (so thanks to the Reddit user from three years ago whose name always reminded me of 5sos but was actually something else)
