The Australian shop Belgium, here you will find along with the artworks, a splendid collection of boomerangs (both traditional and modern), bush telephones, clap sticks, etc...

And of course a vast gamma of didgeridoos in all styles. If you want to learn to play the didge, you can even take a course, along with some fellow-enthousiasts. It's the best way of meeting other European amateurs of the fine Aboriginal culture, and to share your views with them.
