National Gallery of Australia - in Canberra

I'd say it's the National Gallery of Australia, and even if you won't think it's the best, you shouldn't miss it if you're interested in Australian art. It's got works belonging to Aboriginal artists and also to more recent, famous Aussies. There's paintings, sculptures, photography, fashion, furniture and silverware... plenty to se. You can find it quite easily at Parkes Pl, Parkes. The permanent collection has free admission.
