Check out this informative SOUND SYSTEMS of MELBOURNE webpage by El Gran Mono, featuring Minirig and a whole pile of info on some of the amazing Sound Systems that make up the rich scene in Melbs.
To quote the page itself:

In early 2020 we worked with Geelong-based illustrator Rick Chesshire to create our FIELD GUIDE TO THE SOUND SYSTEMS OF MELBOURNE, a limited edition print sold via our website. Based on the UK SOUND GUIDE and other similar sound system pictorials, this was the first attempt at cataloguing sound system culture in Australia.

Melbourne is a city synonymous with the arts and below are some of the sound systems which contribute to the rich vibrancy of this culture.
