We visited here on our first day in Sydney. The museum looks small but has a rich history. We loved the exhibition area on the first floor of the museum about Catalans and indigenous people, and the media introduced here (audiovisual, interactive display, painting, artifacts) restore history. The building itself is worth taking pictures. The entrance is a bit hard to find, in an alley, you have to pay attention to roadside instructions. It takes about 2 hours to visit all areas. All in all, highly recommend visiting this museum in Sydney and it is free!
