The Macleay Museum is a small museum situated amongst the sandstone buildings of Sydney University. The Museum is tucked away on top floor of the MacLeay Building (A12). Although most of the Macleay collection is in storage a proportion is on display and includes selections from the universities Scientific Instrument Collection, Invertebrate Collection (which is regarded as one of the oldest and historically most significant insect collections in Australia), Historic Photograph Collection with images from the 1840's to the 1960's, the Vertebrate Collection and Ethnographic Collection.

The Justice & Police Museum features a magistrates court, a recreated police charge room and remand cells. There is also a gallery of mug shots of Sydney's early criminals and a variety of weapons used during those early years. For those who like the gruesome and the marcarbe, details on notorious crimes such as the Shark Arm Murder, the Pyjama Girl Case and the Graeme Thorne Kidnapping as well as original objects gathered from an assortment of legendary bushrangers, are on display.
