Jim Richardson over at Museum Marketing has quite a comprehensive list of museums that are currently using Twitter as a platform to connect with users. The only problem for those of us in the Southern Hemisphere is that it is very US and UK dominate. So below I've made a list of museums or other cultural institutions in Australia that are currently using Twitter. If I missed you, leave a comment with the Twitter URL.
