Justice and Police Museum, Police and justice museum in Sydney central business district, Australia

The Justice and Police Museum occupies three 19th-century buildings at Phillip and Albert Streets: the 1856 Blacket Court, a single-storey sandstone building with an arched colonnaded portico and Doric pediment; the 1858 police station; and the 1886 Barnet Court. The site also includes a two-storey stone police station with a veranda and a carved "Police Station" inscription.

The Water Police Office, designed by Edmund Blacket, opened in 1856 with a main court and four offices; Alexander Dawson's police station followed in 1858, and James Barnet's second court in 1886. Quarrying at Bennelong Point began in 1853 but gold-rush prices and labour shortages delayed work, and £4,000 was allocated in 1854. The Water Police moved to Dawes Point in 1913, and from 1926 the courts heard traffic offences as Traffic Courts 1 and 2.

The museum holds the NSW Police Forensic Photography Archive, documenting criminal investigations and social changes through historical photographs and evidence collections. Photography became central to modern crime-solving methods and allows visitors to see how police work evolved in Sydney over time.

The museum occupies three adjoining buildings at 4–8 Phillip Street, on the corner of Albert Street at the eastern end of Circular Quay. The 1856 Blacket Court, the 1858 police station and the 1886 Barnet Court are entered from this corner, so allow time to move between the courtrooms, cells and station rooms. The site is owned by the Department of Communities and Justice and run by Sydney Living Museums.

The site's three buildings were erected in stages: Edmund Blacket's court house of 1856 at 4 Phillip Street, Alexander Dawson's police station of 1858 at 8 Phillip Street, and James Barnet's second court house of 1886 at 6 Phillip Street. Sandstone for the first Water Police Office was quarried at Bennelong Point from 1853, but gold-rush prices and a labour shortage delayed work.
