MusicAustralia helps you to find, access and navigate a rich store of information on Australian music, musicians, organisations and services from a single access point. You can find music scores, sound recordings, websites and a range of other music-related material held by a large number of Australia’s cultural institutions or described by specialist music services. MusicAustralia includes all formats, styles and genres, and both heritage and contemporary music. You can also find information about people and organisations.
The site is really great and the search for theme is a good way to find interesting things.
