Location of Boolboonda Tunnel in Queensland

Boolboonda Tunnel is an abandoned heritage-listed railway tunnel at Tunnel Road, Boolboonda, Bundaberg Region, Queensland, Australia. The tunnel is 192 metres (630 ft) in length making it the longest unsupported man-made tunnel in Queensland. Its construction represented an important engineering feat for rail transport in Queensland. It was built from 1881 to 1884 by O'Rourke & McSharry. It is also known as Boolboonda Railway Tunnel and SEQ-6Q 1. It was added to the Queensland Heritage Register on 24 September 1999.

The Boolboonda Railway Tunnel opened 12 November 1883 following a construction period of two years. It was built by Queensland Government Railways as part of the Bundaberg to Mount Perry railway line, constructed to service the Mount Perry copper mines. It took two years to dig and was officially opened on 2 November 1883. The line was deviated in 1960 and tracks removed the following year. The section of the line between Tirroan and Mount Perry closed in 1960 and was removed in 1961.
