Mackay Court House and Police Station, Colonial courthouse and police complex in Mackay, Australia.

Mackay Court House and Police Station occupies a block between Victoria Street and Brisbane Street in central Mackay. The 1938 court house is a two-storey brick building in Georgian Revival style, while the police station next door began life as the 1886 court house designed by Colonial Architect John James Clark. Two brick police residences from 1936–37 and a 1960s watch house and keeper's residence complete the group.

The first purpose-built courthouse on the site was designed by Colonial Architect John James Clark, built by contractor Denis Kelleher and opened on 27 May 1886, with the first local Supreme Court sitting held on 15 June 1886. It cost £4499/8/7 including a strong room and furniture. The present courthouse was built in 1938, and the 1886 building later served as the police station.

The building displays Georgian Revival architecture that reflected how Mackay wanted to present its legal authority to residents and visitors. This style of courthouse was a statement that the city deserved formal, substantial civic institutions.

The site is an active courthouse and police station, so interior access is restricted. The 1886 former courthouse, now the police station, stands at 67 Victoria Street, and the 1938 courthouse faces Brisbane Street on the same block. View the exteriors from the public footpaths; do not enter operational areas.

The site displays layers of more than a century of law enforcement history, with a preserved police station from 1886 and residential buildings from the 1930s. These different structures show how the city's needs evolved and how authorities had to expand their footprint over time.
