4BU Radio Station building, Heritage radio station building in Bundaberg Central, Australia

The 4BU Radio Station building at 55 Woongarra Street is a two-storey brick building with a flat roof and floor-to-ceiling glass on its southern, western and eastern facades. Timber-framed entrance doors with geometric handles open to a ground floor now fitted as a cafe and restaurant. A sweeping staircase with original timber and metal balustrading rises to the first floor, where a door marked "White Lotus Studio" survives.

Bundaberg Broadcasters Pty Ltd was incorporated on 24 July 1935, and 4BU began broadcasting on 16 December 1935 with seven advertisers and a PMG licence costing £25. The station's studios were first leased from Wyper Bros. Ltd, and in 1938 land was bought at Kalkie for a new transmitter, with power raised from 200 to 500 watts. The Woongarra Street building, designed by Herbert Stuart-Nairne, opened in 1957; the station moved to Crofton Street in 1992.

The building displays decorative ribbed ceilings and distinctive wall treatments that reflect commercial architecture trends of post-war Queensland media facilities. These design elements continue to shape how visitors experience the space and recall the importance of radio in that era.

The building is easily accessible and open during the cafe and restaurant operating hours. Visitors can explore the interior spaces while using the dining facilities and see the preserved architectural details throughout.

A painted sign reading "White Lotus Studio" survives on a timber door with louvred vents in the north-west corner of the first floor, left from the years Bundaberg Broadcasters worked in the building. The same floor keeps its original concentric-circle metal light fittings and a sweeping staircase with curved metal balustrading.
