The Museum of Applied Arts and Sciences (MAAS) is Australia’s contemporary museum for excellence and innovation in applied arts and sciences.

MAAS currently operates three venues; the Powerhouse Museum in Ultimo, Sydney Observatory in Millers Point and the Museums Discovery Centre in Castle Hill.

Internationally, the Museum of Applied Arts and Sciences (MAAS) is acknowledged for the calibre of its collection which spans history, science, technology, design, industry, decorative arts, music, transport and space exploration.

The MAAS vision is to be a catalyst for creative expression and curious minds. It is uniquely placed to demonstrate how technology, science and design interact and how they impact Australia and the world.


The NSW Government, through Create NSW is working with MAAS to build a new Museum of Applied Arts and Sciences at Parramatta, expand state-of-the-art collection storage facilities at the Museums Discovery Centre at Castle Hill and retain a creative industries presence in Ultimo.
